The apartment is super central - you can reach almost everything on foot. Therefore, the rooms to the street can be a bit noisy during the nights.
There is definitely enough space for 6 people to hang out and have food together, which we enjoyed to do because the flat is super conformable.
The check-in worked out (with a little delay) and we were even allowed to leave a luggage in the apartment until the evening. J. gave us a warm welcome and explained everything perfectly.
All in all, we loved our stay at J.'s place a lot. Thank you for having us!
