Delio's place was exactly as pictured. A beautiful and pleasant stay. It is on the fourth floor, so there is a nice view of the Santa Croce church. It is also centrally located and nearby all the good attractions. Florence is generally a small city, so you can walk everywhere. Overall, it was a nice apartment.
One thing that was a bit of a problem was that I noticed mosquitoes and left with bites as well. It might be just the season, but that was a big let down. Other than that, it is pleasant and the hosts are extremely friendly and accommodating.
