We stayed for 5 days here and loved the place! The house is a bit old but well maintained. There are a number of rooms rented through airbnb. We stayed in room#5 which is a large and spacious one with a king size bed on the second floor. The bathroom is really nice and clean, it is shared with other rooms so the level of cleanness will depend on you and your neighbors. We did not have any problems with this. The kitchen is huge and has everything you need to cook and a large fridge to keep food. As everywhere in NY and NJ the walls are quite thin so better be respectful and keep noise down.
The house is near Journal Square, we walked back home even late at night and never had any worries. The area looked very safe. Direct train to Manhattan is easy to use and orient.
We have not met Eugene in person but he was very prompt with answering, helped with all our questions and everything went very smooth.
Best deal for budget traveling - clean, nice bedsheets, towels,kitchen, location, has everything you need.
The price is few times lower than hostel in NYC but the conditions are a way better. Highly recommend the place and will use again when coming to visit NYC
