Close to the university, cheap, simple, free wifi.
Also close to the tram (Forum stop) so easy to get downtown (or about an hour to walk at a good pace).
Reception is only open for the advertised times. Stayed for a week and the room was only cleaned once -- fine for me. Small stove and fridge provided.
Had some problems checking in since the reception was not open. Apparently, if you book directly rather than through Expedia, you receive check in instructions, so contact the hotel if you will arrive off hours.
Taxi from the airport costs 40-50 Euros.
