I've stayed at many places in the Mission and I don't think I've ever stayed somewhere as quiet and restful as here. It's located within about a 20 minute walk to everything I wanted to be near (restaurants, bars, the office I was visiting, Dolores park), but while I was inside I never felt like I heard any of the city noise that I'd usually hear. Everything was clean and comfortable and enough kitchen amenities to make some coffee or a quick snack.
Perhaps the only challenge I had in this space was that, as a 6'5'' person, some sections of the unit had low ceilings, including a section that is pretty unavoidable when walking from the front door to the bedroom. This was manageable for me and would hands down tolerate that little detail to be in such an excellently located, clean, and restful place.
