We stayed with 4 people for 4 days here.
The location is very great. You can reach all important sightseeing spots but also bars and restaurants within walking distance.
The stuff at the reception, which is only a few hundred meters away, is very friendly and helpful.
The apartment itself is offers approximately enough space for 8 people. one of the beds we tried was very uncomfortable though so we were lucky to be less people.
kitchen and bathroom were very clean. towels are included. the kitchen could have a bit more items but it's sufficient.
I can recommend this apartment and would come back any time!
