If you want a central place to stay to see the sights of Rome, this is ideal. The location is perfect. After a long journey, you'll be pleased to see that it is literally right next door to a pretty decent local restaurant, with another one across the street. Five doors up there is a mini-market so you can easily stock up on food if you're eating in, as well as snacks for your wanderings. This apartment is 2 minutes walk from Piazza Navona, from there it's another 5 or so minutes to the Pantheon, another 5 to the Trevi Fountain and 15 to the Spanish Steps. Going the other way it's 10 minutes to Castel St Angelo (and the river) and from there you can see it's not far to St Peter's. You can walk to the Vittoriano and the Forum, but on a hot day you might want to hop on a bus. The bus stop is nearby.
We arrived late and Daniele made sure someone (his mum, bless!) was there to let us in and show us round. The apartment is compact (and bijou, Mostyn) but it's very clean, newly decorated and welcoming. If you want a 2/person base for a Rome adventure, I recommend it. Richard
