Stefanos apartment is so centrally located- just behind Piazza Navona and on a gorgeous street with restaurants and the best gelato shop in the world (Gelateria Frigidarium Roma). We didn't use public transport once as everything was in perfect walking distance. On arrival we were greeted by a friend of Stefanos named Luigi, he was a pleasure and checked in with us via Watsapp throughout our stay. He gave us recommendations of where to go and how to book things (thanks Luigi!).
The apartment itself is on the 4th floor (a tiny bit of a struggle when carrying luggage on a 37 degree day!) but shouldn't be an issue unless severely unfit. To get to the apartment is through 5 doors (safe) which isn't an issue but we wish that the keys were explained to us as it was a struggle to figure out which key is for which door- especially when trying to hold melting gelato!. We suggest labelling the keys 1-5 in the order of the doors to make it a little easier. The apartment was clean and a tiny bit smaller than what I thought it would be. The kitchen is tiny but workable for the basics and the bathroom is a good size but the shower is fairly low down and thin. The bed in the main bedroom is rock hard, meaning that two of my party had to sleep on the sofas which were a lot better. This being said, the bed in the living area was very comfy. The terrace is lovely and we enjoyed eating and drinking there in the evenings enjoying the sunset. All in all I would definitely recommend this apartment as it was clean, centrally located and big enough to call home for a few days
