I read through all the reviews, and this place was described accurately by the host and reviewers.
Access to the flat was as described by the host, and no problems were encountered getting into the unit.
The place was very clean and comfortable. You could hear some noises from above, but nothing too loud.
The bathroom was adequate with tight spaces, but worked for me. I'm taller than average height. It was nice not having to duck to shower. All you tall people know what I'm talking about. Also, be aware you may easily bump the shower control and get a cold surprise due to tight spaces.
The kitchen / living room was nice, and has most of what you'd need if you want to cook or watch TV.

Vehicle parking is available on street. Uber and Lyft are always available in this area, and public transportation is available too. But if you decide on public transportation, be warned, this is Potrero Hill with built in stairmaster lol.
The views of San Francisco were amazing. It was a clear night while walking around the neighborhood park. You could see Sutro Tower, the Mission District, Downtown SF, and Twin Peaks.
In closing, I highly recommend this place if you want to be central to all things San Francisco. The hosts were very accommodating. I'll stay here again when visiting San Francisco if it is avaliable. I give it 5 stars.
