We stayed for 14 days at Julia's Apartment to really have time to explore the city. The apartment itself was clean and exactly as described. We liked the new bath room although it does not have a window - but we were aware of that and the ventilation system was working fine. The only window facing towards the street had a new thick curtain, that is not yet seen on the apartment pictures. So it can be made pretty dark inside - good for a long sleep. The mattress was pretty comfortable. Not hard enough for a 6'6" 240lbs guy, but that is always really hard to find. The window is kind of soundproofed and has a mosquito-net. We used the kitchen, washing machine and the dryer - all was working fine. A small drying rack would have been nice to put the clothes on that cannot be put into the dryer. A cool thing would have been a small scale to weigh the luggage before leaving for the airport - good for shopaholics. ;)
The only downside concerning the apartment was that the entrance area in front of the apartment was a construction site as the complete front side of the Brownstone was renovated. So we had to deal with the puddles - some planks would have been good - and the exterior view was not so nice as some other beautiful buildings in the street. Fortunately the workers did not work at all or did start late enough to not wake us up.
Julia is a very nice host who was always reachable on short notice. For the trouble with the construction site she offered a refund right away.
The location of the apartment is very good. Nice restaurants and bars, supermarkets, pharmacies and bus stops are all close by. It is only a three minute walk to 125th station where the 2 or 3 subway will take you in about 20 minutes to Times Square. It is located not to far to the North of Manhattan and not to far to the South - perfect location.
We can definitely recommend this apartment and would like to come back one day.
