We stayed in Donnas apartment 2,5 month. The apartment is super-cute and definitely suitable for long-term stays! It has everything you need (washing machine, dryer, ..). Recently, Donna has new furnished the living room and bedroom and equipped the kitchen with everything (and plenty) you need.
I would say, the accommodation is rather a small, separate house than an apartment. It is located with two other separate houses on the property. All the three can be directly accessed from the street. At the end of the property there is another two-apartment house. Every apartment has its own private yard and we didn't see the other renters very much around.
The apartment is quietly located in a palm-tree-lined street. We didn't have a car over the whole time so we looked for alternatives to get Downtown Santa Monica and around. To walk Downtown SM will take you up to 30-45 minutes. However, Santa Monica offers (besides scooters) )a very good public bike rental system and there are three different stations each in a 5-minutes walk from the flat. In 10 minutes walking-distance you will get to the Metro Rail Station which brings you directly to LA Downtown. (busses are as well available but we didn't use them).
Communication with Donna was very easy and she responded all our questions very quickly. I would definitely recommend this flat.
