We stayed at Martina's house for the weekend. The location is perfect! It's a quiet street but right in the heart of Trastevere where you find a lot of good restaurants and bars.
In the apartment there's everything you need. It's very clean and enough soace for 2 people. Martina was very welcoming and always easy to reach. She replied within minutes and helped with everything. Small breakfast in a cafe close by is included (great cappuccino). The only downside: there's not much hot water and the next person has to wait a while. Overall we had a great time amd can definitely recommend Martina's house!
