I highly recommend staying with Walter and Martina. They are excellent hosts who really care about making sure you have an excellent experience in Rome. When I arrived Walter sat with me to understand why I would like to do in Rome and then he helped me write up some itineraries of places that I could visit that matched what I wanted to do. He is very knowledgeable of Rome and also the local area Garbatella and was able to recommend lots of places where you can get a local experience of Rome.
This is my third trip to Rome, and Garbatella is definitely the most interesting and authentic place I have stayed. Everywhere around you are great restaurants and cafes with much better food than in the center of town. There is a lot of history too in the area which Walter told me about, very interesting to just walk around the area.
The room is exactly what I needed for my trip, it was very clean and comfortable (and air conditioned!!) and had a private bathroom. Overall I highly recommend staying here and thank you Walter for being so friendly and so generous with your time to make sure I had a great visit.
