A charming flat with 2 bedrooms separated by another room and a corridor, so good for privacy. No lift in the building - for us it added charm, but could be an issue for juniors/seniors. Pleasant views from the windows into the streets that are calm at night, though almost central.
Shared terrace on the roof needs cleaning but offers great views (be careful if you clamber onto the roof for better views).
Dario offers pickup from the FCO airport at 50 eur - take it, it's more attractive than Uber (operating at the same rates as airport taxis).
Strongly recommend nearby Il Fico restaurant - especially, their tiramisu and bucatini alla amatriciana.
