Paola's apartment is very nice, cosy with Eastern and Western exposure, friendly neighbours and even friendlier landlords.
The place is stocked with everything that you could need, we even brought things that we needn't have since we could find the essentials in the apartment.
We were five people and we had plenty of space, so if you are a bigger group (5-6ppl) don't worry, there will be enough space.
Paola communicates very accurately but her mother and brother were also very helpful!
Acilia is located near Rome, it is considered a part of Rome. It takes around 15-20min to get to the city by car and by train but you should mind the traffic if you're travelling with a car.
