The place was nice, clean and absolutely fine for young people. People who have difficulties going up stairs should maybe take a taxi. The appartment is close to the center and we could walk to every sight within the centre. One major plus point is the late night check-in (which you can do yourself). Also the people working there are super nice and willing to help whatever you need. They provide you with information about their place and answer very quickly. There was only one thing that was a bit annoying: at the moment there's a construction side next door which is, for light sleeper like I am, a little problem. However, the rest was great :)
