The apartment was fantastic. Incredibly spacious and very quiet.
The check-in was a little bit different than planned but posed no problem. An hour before intended check-in I called one of the people who are in charge of handing over the key as per the instructions upon booking. They unfortunately were not able to be there in person but were incredibly pro-active and put the key in a lockbox which they subsequently communicated to me where they would put near the property and how to get in. This was in fact preferable because it meant being more flexible on our side in terms of checking in. So, bonus points for that.
Furthermore, the hosts also provided a bottle of nice red wine and chocolates. There was lots of coffee and tea available and basic cooking facilities, too.
The flat is nice to hand out in and watch tv, cook dinner and lots of eateries nearby as well as close to Ostkreutz station.
