The main man on reception, Marios, was exceptionally friendly and helpful. I would stay here again just based on his service alone. The room itself was nothing special, but had all you'd really need for a short stay: a bed, a bathroom, a sofa, and a fridge as well as a TV too. It was clean and there was nothing to complain about.
The tram interchange directly opposite was not a noise issue, however if you want to sleep with the windows open, it certainly would be.
The area around the hotel isn't the greatest, though not awful. Between the hotel and the closest U-Bahn station, Keplerplatz, you must walk past a church and small park. Literally every single hour of every day, there are gangs of people hanging around the church being loud, drinking, littering, throwing cans around etc. Our earliest venture past was before 8am, and our latest was after midnight. Both times, and all in-between, these gangs were there.
