We were in the external building (Ivy Street). That building is in front of a construction site - didn't bother us since we're heavy sleepers. the room was excellent, so were the shared bathroom and all else in the building itself.
The breakfast was good, the staff was really friendly.
The location is OK, but there are good and bad streets around. very close to Van Ness station (7 min walk).
A Good price for a good BnB.

Went for our yearly visit to SF and stayed for our third time at Hayes Valley Inn. We love this bed & breakfast. They've got a lovely continental breakfast with ham and cheese, fruit bowl, assorted breads and jams, cereal, yogurt, orange juice and milk.
We normally leave the windows open during the day and by the time we get back to our room, it is late and our room is nice and chilly. We close the window so it is quieter at night. The hotel does have ear plugs for you to use b/c of the street noise.

My friend and I had reservations at this place for 4 nights. We told clerk we are senior citizens and were looking for a safe place. He told us about the shared bathroom and bunk beds to which we had no objection. Upon our arrival , at 8 PM, we were given a set of keys and told to go around the corner to the annex. This annex is located in a dark, narrow alley in front of a construction site with no connection to the main building. We went back and forth , up and down, 3 times, carrying our luggage, between the main section and the annex as the keys would not open the entry door. Finally, the clerk requested assistance from a maintenance man, who also could not open the door. We were left again in the alley, lugging our luggage to the main entrance. We demanded another room and to speak to the manager. The clerk told us that they were totally booked and no other room was available. We demanded to be booked at another hotel. After waiting for 45 minutes, the clerk showed us to a room in the same floor as the reception area which she offered to us for our stay. The manager never showed up or apologized for this situation. What angered us the most was the lie regarding room availability and the lack of response from management.
Besides the above complaint, the place is clean, staff friendly and breakfast is plentiful and varied. If you drive, be advised that parking is a huge problem. But you can park at the covered parking in the corner. Do not park in the uncovered parking, it is a rip off,

My girlfriend and I stayed here for four nights and I have almost nothing but nice things to say about the place. Location wise, you're a 5-10 minute walk to the 47 bus which will take you to all of the major tourist spots. Excellent breakfast AND an afternoon tea time from 4 to 10 with cookies and tea. What a great idea! The woman who owns the place is very kind and helpful as are the staff members.
Rooms are very clean and attractive. Only drawbacks: one shower for each floor. If you stay here, don't wait until 8 in the morning to take a shower. It WILL be occupied. Also, if you're here on a romantic getaway, the walls are very thin and (not to be too risque) but the beds squeak like crazy! Haha. I think you know what I'm talking about. I heard at least two other couples having a a pretty good time as I walked to the bathroom. Other than that, I would recommend this place to anyone. I will definitely be staying here again in the future.
