Brilliant property for a week's stay in Rome. First, to set expectations, this is not a hotel in the American sense. It is a set of rooms in a residential building - a lobby and 5 rooms. I was in room #1, which had a view of the Colosseum out the window.
Accessibility: There is a set of approximately 5 steps to access the elevator, so it is not completely accessible to people in wheelchairs.
Now to my experience: The place is brilliant. Claudia kept in touch with me through Whatsapp throughout my stay. I was able to check in directly after my arrival in the morning by letting her know when I was leaving the airport. I was met by Roberto who showed me up to my room and got me settled. Just buzzed at the front door and he came down, took my bags, and escorted me up. Air conditioning! But I was also able to open the windows and shutters to enjoy the night breeze. One tip - if you have the air conditioning on in the heat, turn off the bathroom lights/fan and shut the door. Otherwise, the fan sucks all the cold air out of the room.
Service was excellent. I woke up to no hot water one morning, messaged Claudia, and it was fixed ASAP. There was a daily housekeeping service, so this isn't just an Airbnb where you're on your own.
Location is next to the Colosseum metro stop. When you leave through the turnstiles, make an immediate right - do not exit the metro onto the street. There is a hall that leads to an upward escalator to the street with the place.
