Emanuela's apartment was excellent. The location was perfect if you want to be by the Vatican City although the metro is only a 10 minute walk away.
We were two couples travelling together and it was perfect, each couple has their own kitchen, bathroom and sitting area. There is air conditioning in all rooms and the windows are double glazed so any street noise was easily blocked out if needed.
Communication was easy, with Emanuela responding quickly to our questions and requests which included allowing us an early check-in.
The apartment was clean and comfortable, restaurants and mini supermarkets nearby.
Would recommend.
