We really enjoyed our stay at Mario's place. The apartment was much bigger than we expected but still had a nice cosy feel. It was spotlessly clean and really well kitted out, especially if you want to do any cooking - there's a hob and microwave, as well as all pots and pans and basic dry food stuffs, plus a dishwasher. There's also a washing machine which is handy for a longer stay. The bed was very comfortable and we slept very well. The location of the apartment is great; close to lots of local restaurants, bars and shops and a short walk to many of the main sites including the Trevi fountain and various other museums and monuments. It took us about 20 minutes to walk to the Vatican and half an hour to the Colosseum but there's also plenty of public transport and taxi links if you don't want to walk. Mario was really helpful (showing us round the apartment and ensuring we knew how everything worked) and communicative (especially as we needed some flexibility with check in and check out times) and also supplied plenty of information on the local area via guide books etc. I'd definitely stay here again!
