The apartment is very good. The location is perfect. Very close to an underground station (Spagna), good restaurants, clothing stores and mini markets.
It has two big bedrooms and a spacious living room. The kitchen is a bit small, but it works.
The space to have shower (box) is very tiny. Both of them (the apartment has two bathrooms). I almost couldn't fit. It's a bit uncomfortable but it works just fine. Besides, it's very hard to find an apartment in Rome with two complete bathrooms.
Our host Giulia was incredible. She helped us with an early check in (it's not always possible) and with the transfer from and to the airport. She was always helpful when we needed to contact her.
I recommend the apartment, keeping in mind that the shower space is very small.
