Sylvie has a beautiful apartment in the center of Barcelona, really close to Las Ramblas (perfect shopping locations) and the metro station Liceu, from where you can reach many places very fast.
The Room we slept in was big and very bright, we also had a big wardrobe with a large mirror and not to forget a small balcony.
Most of the time, we were on the road to enjoy the great city, so we didn't deal much with Sylvie, but she always was very helpful, open-minded and made us feel very welcome :)
We definitely recommend staying at her apartment!
