We just stayed at Chiara's apartment for 3 nights and had a great time the location is about as good as you can get.
The apartment is on the 3rd floor accessed by stairs or lift and is very spacious.
The beds are very comfortable and the towels and linen of a good quality.
We were a family of 5 so didn't really need such big apartment but glad we did so we could spread out.
The second bathroom is a wet room and we only used the sink for cleaning teeth and the toilet. I think 8 adults staying would have more of an issue with the shower in the wet room but for us it didn't matter.
If you don't want any noise at night close the windows and it becomes instantly silent.
Thanks Chiara, great place we would stay again.
