Room was a good size and well presented, exactly as described. We never met Caterina or Elisabetta, they do not live there and were never there. They have a nice elderly lady as a sit-in housekeeper and she only speaks Italian, not a word of any other language. I didn’t hear anything about how to check-in until I messaged them the day before we arrived, the reply was adequate.
Decent location, Testaccio is a good place away from the busy tourist areas and it’s a bit cheaper to eat there and the food is just as good. Local Pizzeria Remo, is one of the best in the city by all accounts, and its 3minutes walk. It’s also around 15-20minutes walk from Trestavere and a wide range of excellent restaurants. Good spot and only 25-30minutes walk from the Colosseum, around 40 minutes’ walk to the Vatican.
