We had a lovely stay at Serena's apartment. She and her sister are both very sweet and helpful. The apartment itself is just as described with two bedrooms and two separate baths. Perfect for our group of two couples. We toured the Vatican one morning and it was very easy to walk there and only took about 15 minutes. We took a taxi to other locations we wanted to visit and never had any issues. There are plenty of cafés and grocery shops near the apartment. We would definitely book here again.
