We just spent 4 nights at Lenny's apartment and we had a very good time. The neighbourhood is quiet and authentic and offers lots of options for eating out. We ended up going to a place called cafe Frederick for breakfast every day, a really great place. The location is great, it's about a 5-minute walk to the nearest subway station and from there about 15 minutes to midtown Manhattan.
Central Park is at 2-minutes walking distance.
Lenny was very quick to respond to all our questions regarding check-in and check-out. The place itself is as advertised, although the living room and kitchen were a bit smaller than we expected.
There is also lots of storage space and more than enough towels.
The only 'issue' is that the curtains in the master bedroom are very thin so the room is quit bright at night. No problem if you are a good sleeper, otherwise I would definitely recommend bringing an eye mask with you.
I recommend this place and would definitely stay again!
