We had a great time at Casina Testaccio. The studio was far more spacious and luxurious than originally anticipated. Its location is great: not in the extremely busy historical centre but in a very nice neighbourhood, which is still close to all Roman highlights.
Sara and Stefano are also - by far - the best hosts we ever had. Everything was extremely well explained and Sara and Stefano have gone to great lengths to make us feel at home, including a personalised map to the city with specific recommendations for great places to visit in the neighbourhood. In one word: wow!
