First, Enrico is a great host. Good communication, instructions and check-in.
Regarding the unit: stylish, well decorated and spacious. Good kitchen, comfortable mattress, good space.
Regarding the location: is located on a street where no cars allowed. So, be prepared to walk with your luggage for at least 500m, additionally, of course is a very old building without elevator, so few steps of stairs ahead.
I visited during the hot June/July summer with temperatures around ~ 35C/95F. The lack of air conditioning was noted (unit is listed without A/C and I booked anyway - so, no host/unit problem).
Another potential area for improvement is the internet speed. Around 30 MB/s and not good quality - I suffer to do some video calls even being side by side with the router (we all know how complex is the internet quality nowadays no matter where we live, so I don’t blame the host honestly).
Assessing the cost x benefits, I would stay again on the property.
