This Airbnb was located in the Donatello, a very nice hotel. The room was clean, and had great views. Valet parking was convenient but did cost $50/24hrs, though this was better than street parking. Overall the neighborhood was safe for the most part, but San Francisco can attract some unsafe individuals and some areas showed this. The only other thing to note is the hotel does require a deposit at the time of check in.
Overall Kalven’s place was a great spot for the price and would recommend it to anybody visiting SF.
