Ilaria gave us exact directions on how to get to her place from the back of platform which saved us from extra walking. Her suggestions for food were all on point and yummy! Also right at check in she gave us all the information abut what to do in Rome and how to get there easily. Her appt is super close to the station and only 15 mins walk from colosseum. I would say it's at a very good location. There are lots of places to eat in the same Street as the joyful guest house.
The room was exactly as in the pictures. A little small but sufficient for us. She was herself super nice and very accommodating of any requests we had. The breakfast was ample with lots of options. She was there in the morning and even cut up fruits for our daughter.
The room was quiet and even though there was another family in other room we didn't hear them.
The living/check-in area can be tidied up a bit but rest all was good about the place... ilaria herself was a very informative, nice and friendly host!
