Positive feedback first: The bedroom and the toilet/bathroom at Rosies place are both very clean. We did not see any other rooms so I can't speak for the rest of the house. The location is also good, there is a tram very close to the apartment which leads to the main metro stations.
Now to what bothered me: Rosie and me had spoken beforehand about the possibility of storing our luggage at her place a bit earlier than the usual check in time.
On the day of the check-in Rosie wrote me at 12:00 to tell me that I could come to her place until 12:30 to drop our luggages off (she would have to leave at 12:30 sharp and if we couldn't make it until then we would have to wait until the official check-in time at 15:00). If you ask me a 30 minutes window is somewhat very short considering we aren't locals and had to find our way there first.
Luckily managed to get to her place just in time. Then we were told that we could drop our luggage off but needed to be checked in by her first before we could get access to our room. She told us to come back by 18:00 as she would not be home before then and without a proper check in no access could be granted to the room.
It had been my understanding that we could drop our luggage off earlier but that the official check in time would remain unaffected meaning that we would be able to enter our room by 15:00 - apparently I had assumed wrongly.
I have to say that the check-in situation did piss me off quite a bit, but that doesn't affect the quality of our actual stay at Rosie's place. If it hadn't been for that, I would, without a doubt rate Rosies appartment with 5 stars.
