My parents and I have spend 10 nights in Harrison's place and we were satisfied on many aspects.
First of all the location is really great, there is a lot of touristic places at walking distance (Madison Square Garden, Empire State Building, Times Square, Highline...), that's perfect to enjoy the city.
Then, Harrison is a great host, he totally fit our needs about checkin and checkout hours.
The apartment is very recent and clean, located in the basement (not lightful), there is a TV with netflix (no cable). As it is recent it misses some amenties to be perfect (saucepan, mug...) but I'm sure Harisson will improve that with time.
Good deal!
