Martin was a very well organized and great host. Upon arrival he walked us through the apartment, gave us some suggestions of places nearby to eat but we mostly just explored the neighbourhood. You are literally a stones throw from the Vatican, ten minute walk from Trastevere (really fun neighbourhood), 30 minutes from the Colosseum even less to the Pantheon etc. We literally walked everywhere and it was fantastic. There is a market right outside your door where you can buy meat, cured meats, fresh fruit etc etc. The kitchen was actually very well equipped for cooking your own meals and we took full advantage of that. My one small complaint was the WiFi in our unit - we kept trying to find the 'sweet spot' which can be quite annoying - in Martin's defense we never bothered to bring it up so maybe he could have fixed it. Overall a great location, well organized host and a very clean, very functional apartment! Would recommend!
