The apartment is as described. Pretty spacious and well equipped (we were a group of 4). There are even some amenities you wouldn't expect. Communication and check-in/out with Anastasia was super easy going. We could also leave our luggage with her on the last day, which we are super thankful for. The recommended Restaurants in the surroundings are great! Try the Osteria for sure. There are also several possibilities to shop groceries around - even a 24h Carrefour.
The apartment is situated a bit outside of the (tourist) centre. Walking to the next Metro station (Vittorio Emanuele) took us about 10-15 min through a not so nice scenery. Walking to Termini also took us about 15+min. Public transport in Rome wasn’t exactly our thing, so we used Taxis instead. A ride to or from the city costs roughly 10€. FCO Transfer with Taxi was about 50€, which was for us 4 cheaper than the 4 Leonardo Express Tickets.
Clear recommendation if you don't need to stay in the middle of everything, which has his advantages (Quality and prices of the surrounding Restaurants, noise, ...)
If we come back to Rome, we will surely look out for Anastasia's flat!
