We stayed here for nearly 2 weeks in Jan/Feb 2019 and it was an excellent stay. Christian is a great host, he is helpful and responsive.
The bed is comfortable and there is a lot of wardrobe space. It was great to have a washer and dryer inside the apartment, as well as a nice bathroom with a bathtub.
It was blisteringly cold outside during our stay, but the apartment was warm and cosy. The sitting room area is very comfortable and there are basic amenities in the kitchen.
The location is also excellent, only one block to walk to the PATH train and then just a few minutes (2 stops) to get the WTC.
There are plenty of decent places to eat within easy walking distance, plus pharmacy and grocers.
Overall I was really happy with my choice to stay here and recommend it to others!
