My husband, our 20 month old toddler and I stayed at the apartment for 5 days in March. We were able to check in few hours before the official check in time which was wonderful.
The apartment is as described and the only thing we can complain about is too small rubbish bin (but that's a very trivial problem). What we loved about the apartment the most was its location. It is right next to the Forum Romanum and Palantine Hill. It takes only 10-15min to get to the gates of those attractions and max 20 min to Colloseum. It takes around 45min walk to get to the Vatican City and no more than 45min to all other attractions in the centre of Rome.
We definitely recommend this beautiful apartment.
