Thanks to Serena and her bed and breakfast, we had a very good staying in Rome. The apartment locates in the student neighborhood close to various buildings of the University Roma Tre. Therefore, there are many bars and good cheap restaurants in the vicinity. The closest metro station is at 5--10 minutes walking distance. The apartment is renovated and has many things for a comfortable stay. For example, one can find everything needed for an Italian breakfast including a good coffee machine.
Serena is a very friendly and helpful hostess. I can recommend this B&B without any doubt.
