Ernesto and Paola are extremely kind and generous. The location is wonderful for access to the Vatican, and walking distance to many sites in the surrounding area (Trevi Fountain, the Spanish Steps, and so much more). Many nearby restaurants, cafe's, markets, and a metro stop if you wish to go further out.
An affordable parking garage is less than a 5 min walk away for $20 per day if you drive to Rome.
Our room was 1 of 3 on the 4th floor, each with a private bathroom (ample water pressure for showering) and a secure door. There is an AC unit in the room, but it was not needed at this time of the year. The room we utilized was spacious for 2 adults, with a comfortable bed, a wardrobe closet, a small table, a mini-fridge, and a couple of padded seating chairs that could be converted into twin beds for smaller children if needed.
The common area serves as the lobby for check-in, and a cozy cafe area in the morning for the provided light breakfast and conversation with Ernesto if you wish to be engaging and share personal stories over coffee, or ask questions re; your time in Rome.
The gem is really the effort Ernesto and Paola are willing to go to ensure your visit to Rome is enjoyable and memorable... I suggest you have WhatsApp installed on your phone to best communicate and receive images from Ernesto leading up to and during your stay. Be sure to leave them a note in their visitor's book, and smile wide for the group photo when you check out.
