This is a tough one. The apartment is very nice but we had some issues in the beginning that were not addressed properly so it is hard to give a full review. So I will do it in 2 parts: The Place, and the Communication/Issues
The Place: Great Place, has everything you need. Lots of places to eat in walking distance. Very close to Roma Termini is you are taking daytrips. Also, close to the Colosseum. Not very close to any of the other attractions. So it really depends on how close to the attractions you want to stay. Most of the others are 1.5-2.5 miles away. We walked some, but used Uber a lot as I am still recovering from Ankle surgery. Beds were comfy, lots of pillow choices. Air Conditioners in every bedroom and livingroom/Kitchen area which worked great but you had to be very careful of having those run with anything else in the apartment. We had the air running and tried to run the washer and we lost all electricity. So now on the issues....
The Issues/Communication: So very first day within an hour of being let in and shown the apartment. This was all very smooth and we were even let in early. We put the AC on as it was hot in the apartment as it was a very hot day. We had just come from 4 wonderful days in Florence and needed to do laundry as our place there did not have a washer. Within 5 minutes of turning on the Washer before we left for 130pm tour tickets to the Pantheon all the electric in our unit went out. We went out into the hallway to see if it was just us or the building. It was just us. So we found the fuse box and everything there looked fine. So we txted our contact for the apartment and waited. We had to leave for the Pantheon so we left and kept trying to get ahold of someone. We finally did and after going back and fourth she said she couldn't get to the apartment and just to call her later when we got back if it was still off. We obviously were not going to do that as we knew we would be out till after 10pm. So we cancelled everything we had after the Pantheon for the day to go back and try to get help with the situation. We knew if it wasn't fixed we would have to find somewhere else to stay. Luckily, one of the things the contact had sent us to check via txt worked, but long story short. If you run the AC, you can not run the washer. Also, they have a fob on your keys that runs the electric in the unit so you can't run the washer/ac while you are gone. It was not a great way to start out Rome.
The only other thing is the showers are very small and the drainage is bad. Otherwise the bathrooms are very nice.
So nice place, a bit far from the main attractions, but if there is a problem......don't hold your breath.
