Our stay at this apartment was mostly a positive experience. First the good: the apartment was clean, centrally located, and amply-sized. The AC worked well. Also -and this was very generous- though we arrived 90 minutes later than we were supposed to due to lines at Passport Control at Fiumicino airport, our host patiently waited for us and was friendly despite the delay.
Our primary objection to the apartment was that the outdoor space is NOT connected to the apartment. The photos, as I remember them, made it appear that the outdoor space was a private balcony, which was the main reason we selected the apartment. Instead it is simply a roof that one accesses through the vestibule by going up a very inconvenient spiral staircase. We did not make any use of the outdoor space during our stay.
The last thing I would add is that the hosts could have been better about replying to queries. On occasion I had to send multiple emails to get essential information for our arrival.
Still and all, a positive experience.
