We enjoyed Mária's place very much. It is comfortable with appreciated A/C and Maria was welcoming and helpful. The terrace was a nice place for breakfast or dinner either before you go on to travel all day or come back after a long and hot trip exploring yet another corner of the city.
We chose this location on purpose since it was located close to Piramide station from which you can reach Ostia beach in 30 min should you travel to Rome in summer and fancy a day on the beach. Additionally, you can walk 30 minutes to reach Colosseum or Trastevere which we recommend since you can explore all the little aisles of the city better on foot than sitting on the bus or metro.
We would definitely consider this place again should we plan another visit!
