Communication could be improved, we had almost no reply from Jullien when we texted him, except from the day of arrival.
The room was supposed to be ready for us at 4 pm, but it was not until an hour after that we were allowed in, since they were still cleaning the room. Luckily, Jullien let keep us our luggage inside while they cleaned.
Transport to almost everywhere in Manhattan was very convenient thanks to the subway, which is right next door. The neighbourhood seemed a bit sketchy at first, but it turned out to be ok, quiet and familiar.
The floor and bed were super squeaky and the mattress made way too much noise even by just sitting on it.
The bathroom was really good and the shower had just the perfect pressure and temperature and all amenities were included. The fridge was super convenient. There were some plug adapters in the place.
Overall the place was quiet except for the neighbour's Saturday night party which kept us up. The front door lock stopped working on our last day so we were basically locked out from the building at night. Thankfully one of the neighbours could open the door for us.
It's true that this is one of the cheapest places to stay in NY, so not everything can be perfect. Some room for improvement though.
