Ari's place is a real treat! You will experience the vibes of the eternal city: many attractions are in a walking distance and you will have the metro nearby to ride wherever you want. The apartment is in a very lively and authentic area, everything (colosseum included) is basically on your doorstep.
The apartment itself is also really lovely, with a beautiful view over the city from a big big private terrace. If you like to cook, the kitchen is very well equipped.
The apartment is also very organized, with fire extinguisher and so on, which was quite impressive! Unfortunately if you have problems climbing up lots of stairs, you might want to think it over a bit.
Ari was very nice welcoming us and taking a lot of time to explain us everything. All in all very recommended!!!
