We had a great time on our trip. The apartment is much larger than the pictures showed and the location was perfect. The Pantheon is just a 5 minute walk away, Trevi Fountain 10 mins, and the rest of Rome's major attractions are all within a 25 minute walk. The area had lots of great restaurants and dessert shops. There is also a taxi pickup point at the Pantheon which made getting a taxi to the airport very easy.
The host's were extremely responsive and accommodating. Our flight was delayed and we arrived after midnight but Piero was up to check us in. We also had a late return flight home and were able to store our bags on site while we explored the city. I would highly recommend this apartment.
