Very clean and great location (highly recommend Wooly Pig for great sandwiches!). Irving Street is definitely walkable when looking for restaurants/going to Walgreens. Parking in front of the place is limited and some neighbors seem to be possessive over the street parking in front of their homes. You may have to park on a cross street and walk.
We booked because we expected it to be a private room with an own place feel (separate from the owners with possibly another airbnb guest staying down the hall). The walls are a bit thin, however, so noise travels very easily making the presence of other guests and the owners unforgettable. We had the feeling like we needed to keep quiet in order to maintain our privacy
Besides noise and parking, its a nice space, very clean and light, and in a good location to explore San Francisco.
