The location of the apartment is great and we loved the neighborhood. We also really appreciated how clean it was. We also appreciated the many clean sheets and towels. There's one full-size bed and a sleep sofa in the living room that was perfect for 2 people.
Some issues that we ran into were a finicky toilet that wouldn't stop flushing, loud neighbors upstairs and next door playing music and stomping on the floors at all hours, and the staircase to get up into the building was unfinished. The floors in the apartment are old and have some small nail heads sticking out so just be careful if you're wearing socks that they could rip. The front door had about a 1-inch gap at the bottom between the door and the floor and while we were there it was pretty cold and windy so we had to cover the gap up with a towel. If you're prone to getting cold, the heaters were confusing to turn on but ultimately worked after about an hour of running. The bed in the master bedroom was also very hard, only about a 3 inch mattress over a slatted baseboard and I wasn't very comfortable. If you don't do well on hard mattresses you should sleep on the sleep sofa.
Overall we enjoyed our stay, though we weren't in the apartment much.
