we booked the flat for 3 nights, we were received by David. the instructions were clear, and David gave us a full explanation on how the flat has to be used. He gave use some tips to find good restaurants and Christmas market.
the flat is at 5mn away from the main train station walking. it is 15mn away from the old town city center walking. or you can take the subway for one stop.
the flat is fully equipped as described in the flat presentation. there is a large living room, we were 8 and fit altogether inside.
everything was great, I recommend
