The location is superb as the main attractions are within walkable distance. The surrounding area is safe. The apartment is big and clean and has everything you need at your fingertips. However, there is no lift in the building, but I think this is not unusual for apartments in the Old Town area.
Monica and Vincenzino are fantastic - they greeted me in person for checked in and explained everything in detail. They also helped me to make the booking at the restaurant. They are very responsive too. I would highly recommend this apartment.
