The room is in a budget hotel and it was a mistake on our part not to research the hotel before booking, but I guess this should have been obvious due to its price compared to other hotels.
It is possible to hear every sound and movement that other people in the building make and the building + room definitely has a funky smell.
Having said that, the apartment is in a great location near Union Square and public transport. Staff were friendly and allowed us to check in early.
