We had a wonderful stay in the flat. Totally fine also for three people. The terrace was our highlight! Bathroom with a window was big and absolutely clean. Wifi was with good speed and was fixed immediately when it was not working in the beginning. Also if we needed something, Gabriele provided us with everything we asked for. Right in the beginning he gave us information where to go and what to see in the surrounding.
Totally recommend a stay in the flat, but you should have a car ;).
