This was the first visit to Rome for our family and we were clueless about where to stay. Tata B&B had the space and amenities we wanted and was out of the hub of the tourist areas. We were nervous before we got there because it was so affordable, but I have to say, we all loved the accommodations. Tata B&B is a 4-bedroom apartment where the owner rents out separate rooms (each with a private bathroom) and the kitchen is shared. The bed in my room was very comfortable, but my kids (ages 18 and 22) didn't find theirs quite as comfy. The kitchen was stocked every day with pastries and espresso. The host, Giacomo, was very helpful. He gave us all kinds of advice and information at check in and was responsive each time I had a question. He pointed us to a terrific restaurant in Trastevere, Da Enzo. Have the lasagne -- YUM!
The B&B is a bit of a commute into the heart of the city, but the bus and metro stops are very convenient. I actually preferred being a little out of the way.
I highly recommend staying here, especially for the price.
