We had a fantastic stay in Paolo's flat in via Labicana.
The flat was very nice, it was plenty of space for me my, father, my sister with husband and their 1 year old son. All communication with Paolo have been very easy, exceptionally fast replies. Upon arrival we arranged for my sister and her family to check-in since me and my father would arrive later that day, everything went fine. Paolo was very helpful, he even provided a high chair and a travel cot for my nephew.
The location is absolutely perfect. Stunningly close to Colosseum, a beautiful sight at night/late evening, and with good connections to buses and metro, which made it easy to get to most of the famous sights in Rome(Pantheon, The Vatican, Spanish Stairs etc.) For those who like walking it's not that far a walk to i.e centro storico or Trastevere. It's also not too far from the Roma termini, it took me about 25 minutes to walk(with quite heavy luggage). All in all a really enjoyable stay, we would definitely stay here in the future.. :)
