We decided to change to CASA GUIDO transfer airport 24/24h, and had a wonderful stay. The information and pictures provided are accurate. Guido is very helpful and friendly. He also offers transfers from and to the airport, which I recommend - it will take you 15 minutes (and it would take more than an hour with the public transportation). The apartment was tidy and clean, there is a thermostat, so you can set the temperature at the apartment to what you want it to be e.g. it was nice and warm. The apartment is charming, the atmosphere is great and the view is just stunning! It's a bit far from the old town, but still within walking distance, if you like walks (:
All in all it was great.
Thank you, Guido for the hospitality and for the help :)
