Two of the bedrooms were downstairs in a basement with no windows. You had to go through one of the bedrooms to get to the shared bathroom. There seems to still be some ongoing renovation work in the apartment. The outside building and the location while close to the convention center is in a bit rougher part of the town. Although nothing happened to us, I wouldn't necessarily recommend it for families with children.
The beds were very comfortable and bedrooms very spacious. The apartment was clean and had everything provided that one could ask for.
Overall, the place is great to stay in for adults.
