I stayed here with a female colleague while on a work trip; everything worked out great for us. The hosts let us have two separate sets of keys so we could come and go as we pleased. There's a subway stop and lots of excellent food options very close by (including a delicious bagel shop that I enjoyed every morning).
The size of the double bed might be a little cozy for folks who aren't dating. My colleague and I didn't mind sharing a bed at all but we did know going in that it would be cozy.
The room has multiple power outlets, tons of closet space and hangers to hang clothes, and wifi that worked great. The bathroom was lovely also. The hosts provided us towels and also tons of travel-size shampoo, toothpaste, lotion bottles, etc just like a hotel.
One small downside: the walls are a bit thin in the building, but I always bring ear plugs with me everywhere, and I am a heavy sleeper, so I didn't mind. However, it is possible to hear other people surprisingly well in the other surrounding apartments (through the walls, above the ceiling, etc) so bear that in mind if you are a light sleeper.
