Collin responded promptly to our initial inquiry as well as any questions we had during the stay. We had a bit of trouble with the lockbox but that no doubt was our ineptitude. The loft is very comfortable though we would mention 3 flights of stairs (one entering the bldg, one from bedroom to living room/kitchen, one to office which we only used to store our luggage). Closet & dresser space was adequate for the 2 of us; W/D was available but we didn't need it. The bed was comfortable and we slept well despite construction noise nearby in the early morning - but that would be impossible to avoid anywhere in the city. The kitchen was ample, with enough plates, bowls & silverware, and there was plenty of room in the fridge for our leftovers. It did take me awhile to find a saucepan to boil water for tea, but it was cleverly hidden in the oven. It was no more than a 20 minute walk everywhere we wanted to go - AT&T Park, SF MOMA, shopping, restaurants, etc. We enjoyed our stay; it was very comfortable and felt like home for the week we were there; we would stay here again.
