I stayed in room #3 and had a great experience. Mary was extremely friendly and helpful with check in and very responsive with communication. The house is very clean and in great condition. There's a shared kitchen and dining area on the first floor and then 2 rooms on the next floor up and another 2 on the top floor with each having a keypad locked entry. The kitchen is very nice and has modern appliances. She also keeps some basics available for guests, like eggs, cereal, fruit, etc and has those labeled so not to confuse with any personal items guests buy.
Room 3 was spacious, had a very comfortable bed, marble shower, mini fridge and microwave and a nice balcony.
Location is a couple blocks from Chinatown and a 15 minute walk to the Moscone center.
Overall, I was very happy with the entire experience!
