This place is in a flood zone- but they told me it wasn't when I asked. No one was there when I came to check in on Monday, I had to come back twice. Manager was very nice and efficient when I checked out. ... Read more

I rented here for a year and a half and overall had an excellent experience thanks to Rainy, the manager, who is professional and on top of everything. Some challenges have been with new staff being onboarded and learning their systems and processes (as is typical of new hires), and the lift may not be available during lunch 12:30-1:30. On the other hand, during my time renting a unit here, the staff has been very accommodating and offered to let me in early when I called to confirm their morning hours. or stay a bit after while I went through my unit. The facility is very clean and driving in makes it easy, though it is a bit narrow for multiple cars to be inside the facility but everyone has been very nice and patient always. I've rented at other chain storage facilities in the past and haven't had the best experience so l am glad I came to rent a unit here after my divorce. Whenever there have been challenges, Rainy has always made herself available to make things right, and her energy and good spirits are always much appreciated. ... Read more

Everything about this place is fantastic! The woman who runs it, Rainy, is incredibly helpful, friendly, informative--every good adjective you could think of. The facility is clean, light, and airy, and the access is exceptional--you can drive right up to the ground floor storage spaces, which is invaluable for those of us who aren't star weight-lifters; you only have to carry things a couple of feet. Couldn't recommend it more highly! ... Read more

Frequently Asked Questions

There is a wide array of amenities available for the storage units that San Anselmo Self Storage - 21 Mariposa Avenue has to offer. These amenities include Indoor, Drive-Up Access, Onsite Manager, 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 San Anselmo Self Storage - 21 Mariposa Avenue can satisfy all of your storage needs. Different sizes here range from 20 to 28 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 San Anselmo Self Storage - 21 Mariposa Avenue come at a variety of prices, starting from $154 per month for typically smaller units. However, larger spaces can set you back up to $184 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!
