Although we didn’t meet the hosts, there was all the information we needed in the apartment. Also, Philipp’s aunt office was in the same building. She’s a very nice lady who always had a little bit of time to chat with us.
The apartment is a little bit small but it has all the amenities you need to spend a few days in that wonderful city. Also, the location is almost privileged: it’s near the center but it’s so quiet at night... and you have several lines of trolley car walking only a few minutes.
The only “bad” thing I can say is that there were too much spiders living with us, and I don’t like them very much. And maybe the place was a little bit dusty when we arrived but there was a brand new dyson to take care of that :)
I definitely would recommend it or repeat the experience.
