It feels pleasant to stay at this apartment. It looks newly decorated and clean, with a solid entrance door and secure locks, high ceilings, nice floor, new furniture, comfortable bed in the bedroom and large wardrobes in both rooms. It has a good shower. 2 air conditioners - in the bedroom and living room - work well. The kitchen area is modern, well equipped (but no dishwasher) and has many useful accessories. The apartment is on the 3rd floor, so some street noise is far down and the modern windows keep the noise away when closed. The shade from tall trees outside protects from hot summer sunshine, and yet the large windows let plenty of natural light in.
The apartment is located in a residential area, which feels safe and looks clean, with a few cafes and restaurants nearby. It's a 6-minute walk away from Piramide underground station (red line, 2 stops away from Colosseum). It's a 15-minute walk through the posh Aventino residential area to the middle of Via del Circo Massimo (opposite Piazzale Ugo la Malfa), where most hop on/off touristic buses stop. Terme di Caracalla is a nice ancient site about 20 minutes walk away, where one can buy the Rome Archaeology Card that includes entry to Colosseum, Roman Forum and Palatine Hill.
The host Diego was very attentive, communicated well, and made sure the stay went smoothly. In his absence, he arranged a professional host lady Annamaria, who welcomed into the apartment, supplied with complimentary breakfast essentials, gave tips on the local area, and was available over the phone during the whole stay. All of it helped to make the trip to Rome thoroughly enjoyable.
