I was very disappointed when I called this morning to get an explanation of my rate increase, which happened in November 2024 and now May 2025, which happens to be about $50. Prior increases have been once a year,which is understandable.I have been here for many years and everybody’s been lovely, great place, clean everything was fine. But when I called today to get an explanation, (Gabe) he couldn’t give me a straight explanation/answer and got an attitude with me and told me if I was unhappy that I could go somewhere else and he could help me find another location. I feel that this was very unnecessary and rude. He told me the standard rate was $400 for my unit and I’m paying $417 and I could not get a straight answer for that. He also told me that my unit would be capped out at some point and then he told me that it would be raised again after that no straight answers nothing resolved, except he got an attitude with me and told me I basically could go somewhere else if I was unhappy. Just blown away! I asked who the owner was and he basically said it would go through him and he would pass it along………The past mangers have all been extremely EXTRAORDINARY….. ... Read more

Overall, a really nice place to store your stuff. The crew working there and the manager were friendly and helpful, the place is clean and we did not encounter any rodents, their droppings or spiders - which is a HUGE plus! Recommended! ... Read more

The storage was the nearest to home, secured, and clean. However, my experience with Gabe sold me on doing business at this location. Gabe was a pleasure to work with. It didn’t take long to find the right unit for me as he was very knowledgeable on what was available and what would fit my needs best. ... Read more

Dollar-focused office staff ruined the experience. We were long-time customers of this storage facility (3.5 years) - it was a positive experience to the very end when the office staff became focused on getting one more day of rent. The entire experience was ruined as a result. We called and gave 30-day notice to Edward on a Sunday. We received no notification or acknowledgement of the termination of the lease, which would have been a professional thing to do, but moreover, would have given a clear date to target to move out. We moved out one day late on a Saturday, as a result, they insisted on charging one more day of rent, even though they were notified we were out. This sort of petty focus by this storage facility undermines the customer experience and reflects badly on the management. Nice job, Edward - you got your $20. ... Read more

There is a wide array of amenities available for the storage units that Mission Valley Self Storage - 4437 Twain Avenue has to offer. These amenities include Indoor, Drive-Up Access, Onsite Manager, Truck Rentals, Contactless Renting, Security Camera, Gate, Parking, Credit Cards Accepted, Elevators, First Floor Access, Multi-Level Storage and Online Payment. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Mission Valley Self Storage - 4437 Twain Avenue can satisfy all of your storage needs. Different sizes here range from 20 to 200 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

Storage units offered by Mission Valley Self Storage - 4437 Twain Avenue come at a variety of prices, starting from $95 per month for typically smaller units. However, larger spaces can set you back up to $440 a month.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
