We really enjoyed staying here. As many mentioned before the stairs can be exhausting but it is definitely doable and it felt like it was getting easier each time you climbed them. The apartement was great, I personally loved the interior and we really enjoyed the big windows with small balconies and this amazing view.
The location itself was great, when you left the building there were a lot of great restaurants and tourist attractions in a walkable distance or even directly around the corner.
Enrico was great, there wasn't any problem with contacting him for any questions we had and the answer always came very quickly.
Definitely would recommend this appartement.
