We had a very nice stay at Roberto's place. Roberto was very approachable and we had good communication before and during the trip. He gave us some good tips for our stay (nice places to visit - we loved Ostie - and other useful things to know). Roberto was also flexible with our arrival and departure times. The place in itself is nice, located near Rome's main train station sith lots of connections to public transports. It was cool and also had an A/C system which was very enjoyable due to the very hot weather we had.
