Make sure to clarify where to pick up the keys before you arrive as will be left with someone else. It took us 3 hours to check in with a lot of incorrect instructions and difficulty contacting the host and the 4 other people involved with handing over the keys.
Should be easier to check in as long as you ask host to clarify where the keys will be for your check in.
Otherwise very clean comfortable apartment, convenient location right next to the tram.
