Serena and Maurizio's spot is a gem! Great location, literally right in the heart of shopping -- we stepped out the door and crossed the street right into a shoe store! The space is huge with 2 bed, and maybe a 1-3/4 bath. The main bath is huge! But if you're traveling with 4 grown adults with this set up, it may be a little difficult with the 2nd bath -- think, mud room fitted as an all in one toilet/shower stall. When you have multiple females getting ready to hit the town, that 2nd bath can be a crutch.
If it hasn't been stated enough, this residence is located on the third level with no elevators to take if traveling with heavy/multiple suitcases. Fortunately, they had one of the guys to help carry one or two of our bags.
Place was clean. Thoughtful amenities such as robes and slippers were provided. And, after situated, Maurizio sends you a list of resto recommendations! We were able to enjoy at least 2 spots off his list so I can't wait to return and hit up the rest of his recommendations. Please visit the gelatoria around the corner, Fatamorgana, because it was the best gelato we've had in Italy!
We didn't encounter any issues during our short stay, so I can't speak for their responsiveness but upon our check-in they quickly responded to a simple question.
I would definitely recommend them if you're ever in town!
