Italy is beautiful, no two words about it :) All the tourist attractions from my country would fit within one of Italy's region, with room to spare.
Ronzo-Chienis is a good "basecamp" for some exploration of northern Italy. We were able to see Venice, Verona, dolomites on three occasions, various lakes in the area, castles, villages, and mountains surrounding lake Garda. Ronzo is placed relatively high in the mountains though, and take that into account. Roads are narrow and winding, road to Arco would be better negotiated with side mirrors fold flat :) Relatively "fastest" is road to Loppio. "Fast" being loose term here.
I love driving and mountain roads, but my daughter got nauseous after three minutes of more spirited driving, so I had to resort to casual rolling around. Anyone who saw olive green Alfa Romeo Crosswagon majestically taking another turn - sorry. Poles usually like driving fast, and Alfas are great handling cars. I just had to go slowly most of the time ¯\_(ツ)_/¯
As to the accommodation - it's absolutely sincere. We were afraid that maybe photos are exaggerated, or the place is near noisy street, or something, but no, nothing like that. Almost idyllic village, well furnished apartment, clean, quite roomy, with sort of balcony and terrace at one's disposal. Couldn't be happier about it.
Our hosts - friendly, not intrusive, english speaking, very nice people.
I would, and I will recommend staying in Mirko's place in a heartbeat.
Did I mention Italy is beautiful? If You haven't been there, go visit it. Now.
