This was only our second stay in an Airbnb. Based on this experience, we'll definitely keep using this service. Roberto was very nice and responsive to the few requests we had. I originally didn't think I'd like the bathroom, but Roberto definitely made the best use of a small space. We may incorporate some of his ideas when we remodel our bathroom (heated floor and mirror, Toto Washlet toilet, doorless shower).
Roberto has tried to think of everything you might need. The kitchen had everything we needed for our morning coffee except for half and half, and that was easy to remedy because there are so many markets nearby. There was ample storage spaces for all our clothes. There was shampoo, conditioner, lotion, Q-tips and even Band-aids.
Other reviews mentioned the bed is comfortable. My wife loved it, but I'm a 200-lb side sleeper, so it was a little firm for me. There were many blankets available for cooler nights (not when we were there).
We live in a quiet neighborhood, so please understand that's where I'm coming from when I say there was a little noise. It was maybe just slightly more than you would get in a hotel room. The neighbors were quiet, but the ones upstairs did drop something large on the floor at 2 AM, and someone also repeatedly let the front door gate slam shut. The trolley also woke us up a couple times when we slept in later.
Finally, the room can get a little warm, especially in the morning when the sun shines in those big, beautiful windows. However, Roberto was kind enough to think of providing a fan, which we used often. NOTE: We were visiting in late September when temps can get pretty warm in the SF Bay area.
We will definitely stay again if we visit SF in the future. The Mission District is the best area to stay in. It's relatively quiet but close to everything fun. We walked a little over 100 miles in the week that we were there, so we saw just about everything, and it's definitely worth visiting.
