Daniella always responded to my questions though I never met her. The cleaning lady gave me the keys and waited extra for me as I arrived extra early.
The room and bathroom is as advertised. 2 other groups were staying there too but it was enough space for all of us. Although there was a tv in the room it did not work as now channels could be received. This was a little downturn after a long congress day.
The neighborhood is ok with trams and busses in front of the door. Bike rental is on the opposite of the street though you can not return the bikes on saturday evening or sundays. So renting bikes on weekend trips is not recommended.
A nice bagel cafe (beans and bagels) is 100 m away which serves really great hummus bagels. I recommend that for breakfast to everyone.
