We were able to check in earlier with no problems. The location of the apartment was great! Walking distance (on a hill) to the city centre, Yellow Bus hop on and hop off bus start route, tram (old and new), rooftop bar, shops and restaurants and many other places.
The flat itself is small as others have said. The bathroom is small, the shower takes a while to fine tune the temperature if you can find it. It is strange that the bathroom window allows you to see into the bedroom! There can be a smell if the windows are closed during the day.
The kitchen is a simple galley with living room large enough for two.
The flat can be noisy when the windows are open.
Overall it was a good place to lay our heads at night!
