We spent a week in Rome and had every day several sightseeings. The best advice for sightseeings in Rome is to book as many locations as possible online. The entrance to Collosseum and Vatican Museums is a little bit stressful.
The appartment ist about 3 walking minutes away fom a bus stop where different bus lines run. Every day we were on the road with bus. It is easy if you are informed about the rigt line. Sometimes bus lines are not on time. Especially you have a meeting it is necessary to calculate enough time. Of course on the weekend all showplaces are overfilled.
Piergiorgio and his family are very friendly. The appartment lays in a side street of Via Gregorio VII, a main street with corresponding traffic. It is nice, spacious and clean with a small balcony. Air conditioning was running perfectly. We ejoyed every day sitting on the balcony and drinking some wine.
