Marco's flat was great. It is located right next to Termini train station. It took us only 5-7 minutes to get there by walk. The flat was big enough for three people (even four people). Marco prepared one bottle of wine to welcome us. We felt so special haha He also gave us good travel tips on how to browse Rome. He was very flexible and caring host. Marco kindly agreed to extend check out time for an hour because of our train time. He was easy to reach while I stayed in Rome and very helpful.
