This stay in the Mission was great. The apartment is designed beautifully, and definitely the most beautifully designed AirBnB I've ever stayed at. The ceilings are tall which gives the large apartment and even bigger feel. The outside deck behind the kitchen is also incredible -- it was much bigger than the photos made it seem, and we spent most days out there drinking our coffee or relaxing in the afternoon.
The communication with the hosts was great. They were always quick to respond and were very nice.
My only negative comment was the area itself. The positives: It's centrally located and extremely convenient. You're a block to Valencia street with a ton of great restaurants and cute shops, and close to a lot of small, great food spots on Mission street as well. Other than that, the area can be a bit sketchy at night. A lot of homeless in the area (which is true of a lot of SF), and even though I never felt unsafe during the day, at night there were many times I did not want to walk our dogs or be outside. The actual neighbors are the sweetest people, however, and frequently said hi to us when seeing them on the street.
