Alessia is a great host: all our questions were answered quickly and she was very helpful. Regarding the check-in times she was completely flexible. She even made us a nice farewell gift because we fixed something in the apartment while we were there!
The apartment itself is functionally equipped and has everything to accommodate 2 persons for a great stay in Arco. The by far best thing about the apartment is the view: it's just absolutely stunning. It is higher than all the surrounding houses and on the top floor so you can look above the whole valley, see the surrounding mountains and even a bit of lake Garda. We were really amazed by that view. The location is also great: it's not far from the center in an authentic Italian neighbourhood with narrow streets and a great pizzeria!
Another thing we didn't expect from the description: additionally to the parking space outside you also get a garage where you can put your gear. It also has 2 city bikes that greatly helped us in getting around the town and the valley.
Arco itself is a great base for all the things you can do in the Garda region: climbing, biking, hiking, via ferrata. We had a great time in Alessia's apartment and would love to come back some day.
