Thank you Casa de' Fiori it was an amazing weekend! The location is very good, you can explore the most visited sightseeing from here only by foot (Vatican, Spanish Steps, Colloseum, Piazza Navona, Trevi Fountain, Foro Romano, Palatine Hill, etc.) The connection is quite good from Airport: Fiumicino - Ostiense by train, than you take bus 280 or 30 and you are there and it costs you only 9.5EUR.
The staff is very helpful, we had late check-in and everything went well and easily.
