Franca was a very nice and responsive host. Arrival and departure were perfect as we could drop off our luggage either at the apartment or at the concierge.
The apartment had two problems: wifi not working (only edge connection) because the monthly limit of Gigas had expired, and hot water only for barely 1 shower in a row. Franca tried hard to get this solved, but we got wifi back only on the last night as it was a new month, and the hot water was fixed on the last day too.
Apart from that, the apartment is simple but convenient with the equipped kitchen.
The location is great since you are on the main metro line of Rome and close to one of the four major basilicas. However, if you really want to be in the heart of Rome you should look for something closer to the river.

In a word, we really enjoyed the location and how wonderful Franca was, but the 2 problems made it not worth this amount of money. If these problems are fixed, then this is a good deal!
