Daniel was an excellent host, very accommodating (we needed to check in a bit early) and thoughtful (he left lots of amenities including bottled water, nice shampoo and conditioner, plenty of towels, etc). The apartment was clean and nicely decorated, and the pictures online are very accurate. I stayed there with 4 other women, which was a bit crowded (only 1 bathroom) but basically worked out fine. For 4 friends total it would be great, though keep in mind that one of the bedrooms is a loft and has a curtain but no door, so two couples might be uncomfortable. The location is very close to the Moscone conference center, but be aware that the neighborhood does have a LOT of homeless people (which I think is true for a lot of San Francisco). I wouldn't recommend walking around alone, particularly at night. Overall though, it was a great place and we had a really nice stay!
