Mara was absolutely lovely, very helpful, she helped us with the train timetable, infos about where to eat around the flat, and provided our little baby with a nice little bed, a high chair and various toys. There was even a night light for him and a plastic bathtub! She replied very quickly to the messages and was charming.
The apartment was even better than on the pictures, with lots of space, nicely furnished and comfortable. The tram is near and goes directly to Piazza Venezia and as it's one of the first stops, you get to sit down which is great. There is a little mini-market very near.
We highly recommend staying at Mara's, it's very good value for money and a nice memory.
