The apartment was well located (close to Termini, grocery store, great gelateria and tram/metro stations) even though the neighbourhood itself was left to be desired. It was clean and cozy, had towels and extra sheets/blankets as well as many recommendations for things to do. The host was very nice and communication was easy. The very big issue we had, having stayed 10 days there, was that the WiFi was completely unusable. Although the host did try to fix it twice (there is no WiFi router in the apartment, just a WiFi signal extender), it never truly worked, which meant we had to use our own data and then some, at our expense. There is air conditioning but only in the bedroom and although that works great in there, it does not cool down the rest of the apartment at all. The building itself has an elevator, but the sounds from everywhere travel throughout, which means that you can hear what's going on in the common areas (stairs and all) very clearly, very loudly.
All in all, we were somewhat disappointed with this apartment, as it had good potential.
