Staying at Miriam's place in Trastevere was a wonderful experience. It was easy to take the #75 bus from the train station. We were kindly met at the bus stop, a short walk away from the apt.
It was delightful to stay in a neighborhood with excellent bakeries and restaurants and walks with views above the city nearby.
Coffee and fruit was provided and we loved starting each day with breakfast on our private balcony. The bed was comfortable and there was also a living room. And it was quiet. We also appreciated the quiet air conditioning.
I would highly recommend staying here if you're happy to be a little bit away from major sights. But they are easily accessible by bus.
