The house is SPACIOUS and PERFECTLY LOCATED (walking distance to the B and 4-5 lines which take you all over Manhattan in a few minutes... and more lines). Fort Greene is a also a great neighborhood itself with lots of shopping options, the park and the BAM. The house itself is very nice, arranged over three floors with a large yard on a quite street. Check in was completely painless and Jon was super responsive when we had an issue with internet.
Overall it's a great house and a unique experience to pretend to live in such a coveted neighborhood. However, I ended up paying about 800 per nigh because it was the holiday season and I am going to write a review based on this price.
There are a few things that COULD BE IMPROVED though. First, I somehow convinced that this would be a house in which Jon lives but this is not his primary residence. As a result, the house feels like a rental with older furniture and rather empty (plates and most cups are made of plastic for example, and I doubt anyone would live like that).
Apart from salt and a few spices, it was hard to find something to cook with so we had to buy pretty much everything to make French Toasts in the morning for the kids. It would have even nice to find sugar or syrup for example. Other than that, the kitchen is rather well equipped with pans and a nice gas range.
Finally, my main sore point is about comfort. Were were two adult couples and two young kids. Kids slept very well and had basically all of the third floor for themselves, including a private bath with a tub. This was great!! The master bedroom was spacious and quiet and the bed was ok. However, the second bedroom was not so comfortable and rather small. Two nights were probably the most we could take in it. The bathroom is great though: excellent water pressure, hot water for everyone.
Also, as we were about to check in, Jon let us know that the washer was broken. This was of course not a problem but I believe that it had prevented the cleaning person to wash the linens, which smelled like someone else had slept in them. The towels also smelled moldy. It's pretty clear that all were thrown in the dryer without a wash and I would have preferred if we were told about this.
