We had a wonderful time at Riva and in the AirBnB. Everything was clean and there was everything one could need for a short vacation!
Because the flat is provided through a different rental service everything is very professional and safe.
The only drawback was the noise because the rental is directly in the centre and the trash pick up in the morning etc. So there was only one really quiet morning, but nothing anyone could change.
All in all it is a great place to stay directly in the city with everything you need in 5min walking distance.
(Especially the restaurant directly in front of the entrance is very good.)
