The location is great for LES. Steps from the front of the building are several restaurants. Three minutes to the JMZF trains. The apartment is two floors up when you enter the building. From the street there are also 10 or so steps to the entrance. The bedroom is very quiet, a rare find. No street noise at all. Once in a while you can hear the neighbors, but definitely not in the late evening. The bed was perfectly comfortable. The bathroom is interestingly shaped, accessible via the bedroom. Good water pressure and instant hot water. Tons of sheets and towels provided. Heating was good for 50's weather. The couch in the living room was comfortable enough, although one end seems to be slanted so personally I would fix that up.
Generally the apartment was clean, and it was nice to see that this is important to the host. Visually some objects could look nicer, and perhaps the same goes for the staircase, but overall no issues. Wifi was great.
I liked that the host really cares to have guests who will maintain the apartment in good shape. She was also extremely... unbelievably... flexible when my schedule became unpredictable. Good communication.
