Guido's place is just as pictured, clean, and spacious. The blackout curtains in the bedrooms were particularly nice since we were jetlagged and wanted to be able to sleep in. The apartment is in a great location within walking distance to both the new and old cities and many restaurants. Parking at the apartment was 6 euro per night and we didn't use our car while there since the roads were narrow, confusing, and parking wasn't easy in the city. Guido stayed up late to meet us after our late flight, which we really appreciated.
Note that there are 3 keys required to enter the building and apartment and you only get one set, so if you are in a larger group that won't be coming/going together, you'll have to do some extra coordination or be locked out. Overall this was a great stay!
