We loved staying in Simona's apartment. The location is amazing, all of the major sites are easily walkable and it is around the corner from amazing restaurants that don't feel touristy.
Simona is so kind and a great host. She arranged a car for us from the airport and was so nice to give restaurant recommendations and how to get a taxi!
The apartment is on floor 3, but there is an elevator available so that you don't need to carry your bags. The view from the apartment is so beautiful. I highly recommend this listing.
