A few thoughts on this wonderful place:
1. If you are an art history lover, or fan of Raphael in general, be aware that he will be one of your closest neighbors. The location is nothing short of astonishing.
2. Every major site in Rome is walkable from here. There is also place to pick up cabs on the other side of the Pantheon. It's very convenient and hassle free to roll the luggage over there, take a cab to Roma Termini, and then take the Leonardo Express to the airport.
3. Runners will appreciate the proximity to the Tiber. A morning run along the river before the city wakes up is something to experience.
3. This is a great place to say if you like to eat. The Trastevere is a short walk and there are some good restaurants closer as well.
4. Kitchen amenities are very good with everything needed to cook a good meal available. There is a Coop nearby and additional produce markets in the Trastevere. Italian restaurant culture involves eating late and unhurried. Thus, having the option to cook a quick meal at home instead can be very helpful if one has a lot of early morning activities the next day.
5. Giuseppe was great with communication and check in was seamless.
