It was a huge pleasure to stay at Luisa's place. The apartment, just as the host, is very charming. Everything is nicely and originally decorated and complete with all one can need.
The area is quiet and authentic, giving you a relaxed buzz and a feeling of how Romans truly live. The narrow, paved streets and old buildings help create that atmosphere you would expect to find when visiting Rome.
Trastevere is also a neighborhood on the rise, with lots of lovely little eateries, plenty of bars and gelato shops, a bohemian feel and significantly lower prices than the more "touristy" center of the city. All the while being within walking distance of all the major sights.
Right around the corner from Feline House is the Botanical Garden, which I strongly recommend visiting - very pretty and quiet.
Luisa was such a warm and friendly host, greeting us with a huge smile when we arrived and giving us a thorough tour (with explanations) of the house and advising us about how to go out and about Rome, what places to see and how to get there. She had booked a taxi to pick us up at the airport and everything went very smoothly from there on. Oh and we loved all the art in the apartment!
Would certainly recommend Luisa's place to anyone wishing to have an authentic Roman experience, to be close to the main sights but tucked away in a quiet alley so that the noise and traffic of the city don't bother them.
