We stayed three night's at Elena's apartment and had a great time. Her co-host Federica was really helpful and communication was good. The apartment is in a beautiful historic building and is spacious and well organised with everything you need. The beds were really comfortable and we slept well. As others have said, there is some noise from the streets, but via Parlamento is not a busy street and it didn't affect our stay.
The location was wonderful, easy to walk everywhere and there is nice bakery 2 mins away for breakfast and a large supermarket 5 mins away too. We would definitely stay again - thank you Elena and Federica!
