My girlfriend and I booked this apartment at the very last minute, for a month long stay. For the price, and very last minute booking, we were happy with the place.
The immediate area of the apartment is a bit touristy (with bigger hotels nearby) but it's conveniently located (just blocks from the Spanish Steps) and walking distance to many smaller, quainter neighborhoods. It's right next to a train stop.
The apartment itself was fine. It had nice light, and was more spacious than the pictures make it seem. It had 3 couches, instead of the two pictured, so it was a little tight, just FYI.
Antonello was very kind and communicative. His mother let us into the apartment, and explained everything. Antonello followed up, and made sure everything was fine. We reached out to Antonello for a few other things throughout our stay, and he was pretty responsive and helpful. The washing machine was broken, but Antonello let us use one in a neighboring apartment. The oven may have also been broken, but we didn't have a need to use it.
