Relais Palazzo Lodron - Guest House is a great hotel.
It's amazingly beautifully located, just 10 minutes from downtown Rovereto (10-15€ by taxi). My room was great, everything is nearly perfect (access to the very nice pool and sauna area is through the garage). But the best thing was the amazing staff that helped me with everything I needed in a great way. I can also recommend the nice restaurant just around the corner, Osteria dele Strie, I had two great meals there and would love to come back if I am ever in the area again (definitely worth a 1 hour extra drive). I am planning to come back when I can.
