Josette and Nino are very reliable hosts, make our stay very comfortable and easy to keep in contact. Also, they can help you to book transportation, tours, etc with a fair price ( you can rely on them, I double check with other places just in case:). Also, they will send you their own online mini guidebook that I think was very helpful!
The property was great for our family of 7 (1 boy of 13 and twins boys of 9), modern compare with other apartments in Rome (keep an open mind in this because Rome is a cultural but an old city!) and with the basic appliances for us especially the washer AND DRYER machine. Location close to the termini station was great, you can find train and bus station in walking distance to go anywhere.
The streets around were a little dirty and with graffiti that may me worry at first but then I realize that was safe and there were a lot of similar places around Rome.
