Kevin was very easy to speak to and instantly helped when I had small questions / issues.
The location is good: close to Castro Street, shops, restaurants, etc.
The place itself I must say I was not a fan of. It is small. Ok for 1, 2 people but smaller than the pics made me think. It is quite noisy because it just isn't well insulated. The Caltrain is very far away yet you will hear when a train comes to MTV. And they come. All day. All night. The bathroom window did not close at all, so in February, it got really cool in the night. There's one heating system in the apartment. It heats up very strongly, but not in a very distributed way. So expect to be either hot, or cold depending on whether the heat is on or not.
The nice thing is that the kitchen and bathroom had a bunch of things that helped you get started (milk cartons, tea, soap, shampoo, etc.)
TLDR: Great host, great location. But I will be looking for another apartment, if possible from Kevin, next time I'm there.
