Todd and Amy's apartment is smart, tidy, comfortable and well located. You will have everything you need for a short stay. We found our time to be comfortable and peaceful. As mentioned by others and the hosts themselves, there is a small amount of noise coming from the house above but this did not impact our stay in any way. Most of the time we are out of the apartment exploring the city or asleep anyway!
The area around the apartment is the best in SF if what you are looking for is trendy cafes, bars and restaurants. The main tourist sites in the city are a short ride away by metro or trolley car.
I would recommend this apartment to couples or pairs of friends visiting the city – it is money well spent and provides an excellent base for your stay.
