We had a wonderful stay with Andrea and Ester - they are wonderful hosts!
There was clear regular communication prior to our arrival, and Andrea had arranged a car service to and from the airport so literally we had no concerns on arrival at the airport.
Ester met us on arrival and provided a thorough overview of the apartment (which was incredibly clean). She even had information available on nearby restaurants that they had vetted themselves as well as local tips for the sights. There were some items placed in the kitchen and fridge so that we could have breakfast the next morning. The apartment had wifi and a washing machine.
The apartment is located walking distance to pretty much everything (many sights, shops, restaurants, grocery store, the river) and it was so easy to just get out and walk around to discover things.
Overall we had a wonderful stay and would highly recommend this apartment for your stay in Rome.
