I stayed at Gordon's apartment for one month and I enjoyed my stay.
Positives:
A spotlessly clean apartment - definitely the cleanest apartment I have stayed at.
The temperature of the apartment was perfect during my stay - it was warm and a consistent temperature in each area of the apartment.
The apartment is stylish, comfortable and cosy. The bed is very comfy and there are good curtains to block out the light. Both the sofa and desk are great to use.
The shower has great pressure and good temperature adjustments; the bathroom overall is in great condition and spare towels were provided.
The kitchen has all the utensils needed for up to two people and everything I used worked well.
The Wi-Fi works perfectly and didn't cut out once during my stay.
There is a pay-per-use washer and dryer in the basement.
The location is exactly as described - there is noisy traffic outside but that is the norm in Midtown Manhattan; the subway links are fantastic and very close by, Central Park and other main tourist spots are within walking distance; there are lots of restaurants nearby.
The apartment is in a safe area and is a secure building.
Gordon was a very helpful host - he responded quickly to messages and if he was not around he had others who were able to assist. He helped to carry my luggage up the stairs when I arrived which was a huge help to me! He also let me know when mail arrived for me after I had left the building.
Improvements:
The TV can be frustrating at times - not turning on/off easily.
The hairdryer was missing despite being listed on the amenities list (this is difficult for those who wouldn't have a hairdryer with a US voltage).
The kitchen is different to the one in the photos I originally saw (this is only a heads up for future guests so they are not surprised as the kitchen was still great to use).
The apartment lacks natural light - again this is not a major issue considering the positives of the apartment.
For the price of the apartment a few additional supplies could have been provided (e.g a spare set of bedsheets, a duvet cover/blanket, more toilet paper for a month's stay, garbage bags).
These negatives are all easily areas that can be resolved to make this a 5 star apartment. Overall I would recommend staying in Gordon's apartment.
