Someone said it already, at the beginning there was a weird smell from the small bathroom, but it was no big deal.
Opened all the windows for a while and it was fine. Everything else is great.
Rooms are all great. Communication is easy. Subway is right there and takes like 4 mins to the city center.
P.S 5 min footwalk away is a great pizza place. Prob one of the best i ever ate
