We really enjoyed our time in this apartment. The location is very good, and even though it's close to the action is relatively quiet. As others mentioned, there are a lot of stairs, but it's not a surprise and manageable. If you're a light sleeper, be warned that the church bells start at 7AM each morning. I really liked Amedeo who met us and promptly took us to the apartment; he even carried my daughter's suitcase with him!
To make it even better, I would suggest a welcome basket which has some water, snacks, coffee, or light refreshments. In most other rentals, we have received this and it's a lovely surprise when you arrive. I'd also request more than one dishcloth and dishtowel for guests that stay multiple days.
Overall though, this was a great apartment where we could really have a lot of space. And, we really enjoyed the roof-top terrace. Thank you!
