Instructions to find location were great=however where in building, how to get in etc was not detailed enough. Although we advised of our arrival time-no one there and had to wait 10 mins for someone to arrive to check us in/give us access.
We got into room and naturally with it being 35 degrees out-we put on air conditioning. We left for an hour and a half and upon our return got a note "inside our room" saying we had left it on, now it was leaking and we could now not use it at all. How does running it for 1.5 hours regardless of if we were there or not mean "we broke it". We called the contact for the site and got no answer and as such got no additional room with air-which is what we paid for! Also keeping windows open is a concern as it is noisy and there are mosquitoes (plus it was very hot out!).
The location is perfect for all you need, facility was very clean and outside of the issue with air was well appointed.
However, not having standard check in is an issue and naturally not being available when there are issues with the facility is also a huge caution!
NOTE: although taxi's know where the Piazza is, it is very small roads and hard to get there. The day we arrived was a festival so they couldn't take us to it and pulling cases on these cobble stone roads is hard to do. On pick up, taxi did get in but got into a massive fight with 3 other vehicles who were not please having to wait while we loaded our luggage in the trunk!
