Roberto and Claudia were very friendly and welcoming.
Roberto met us at the apartment and showed us where to go/how to get there and left us with the keys and let us get on with our day.
They were flexible with our arrival and leaving times and the airport shuttle they arranged for us was both cheap and useful.
The apartment itself was quite a bit smaller than I had expected, but there was plenty of room there for everything we needed. When we arrived it smelled damp and the sheets were slightly damp to the touch. The apartment could do with a little TLC - a lick of paint here and there and the sort.
The location of the apartment was very good - the colosseum was about a 10 minute walk (it looks closer than it is)
Overall though a pleasant stay and a great location
