One of the best Airbnbs we've stayed in. The location is excellent - you are steps from all the cafes, restaurants, and night life of the Gaslamp district, but the apartment is a block away from the main drag so not too noisy. You do hear sirens and some traffic but nothing crazy. The building itself is well maintained and very quiet.
On our first night, the smoke detector started letting out a piercing chirp every 30 seconds or so because the battery was dying...of course this began around midnight shortly after we had gone to bed. Due to the high ceilings in the unit we couldn't get up there to disconnect the smoke detector ourselves, so we texted the host, and within 15 minutes someone came over to fix the problem. The host's quick attention to this problem was very much appreciated, especially given the late hour.
Other things we appreciated were the French press coffee and plenty of shampoo and soap. Overall an excellent Airbnb that we'd certainly come back to!
