We had a wonderful stay at this flat. Susanna, and her local care-taker, Sylvia, were very easy to work with. The flat is as described and shown in the photos. It is actually quite large for a one bedroom, and being newly renovated and nicely furnished it is very comfortable and pleasant with all the amenities needed. The village of Gavazzo is rather quaint, and a nice break from the bustle of Riva. The local restaurant at the end of the street is authentic, and excellent as well. I would stay here again, and recommend it.

A few things to note:
The flat is on the first floor and shares the entry with the second level flat. The shared entry is rather large, and was big enough for us to store our three bicycles.
Parking is at the end of the block, in a dedicated space, but is outdoors and about one block in distance from the entry.
The directions to find the flat are accurate but difficult to find in the dark (as we did), so best to arrive in the day light!
The roadway through Gavazzo, and past the entry is VERY narrow. We loaded and unloaded our car in front of the entry, but with minimal space to pass through the village as there is an arched passageway. If you have a larger than average car, you will not be able to drive through.
The flat has a large terrace facing the lake, but the lake is only visible from one end. But, it was great to have for eating and lounging outdoors.
Gavazzo is located on a rather steep hillside. If you cannot walk on hills, or you wish to cycle with children from here, it may not be ideal for you.
The flat is located above a switchback on the road that carries traffic to Tenno. Having new windows, the traffic noise is no problem if the windows are closed, but during our stay the weather was very hot and we needed to keep the windows open at night, so traffic noise was a bit bothersome at the early hours.
There is effectively no wi-fi. I was only able to find the local wi-fi three times in nine days, and even then it worked moderately at best. There is fast, free wi-fi at all the tourist offices.

That all being said, the flat is very nice and conveniently located, and I do recommend it to most anyone.
