It was my first experience with bnb and it worked really good for me.
Valentina´s house is a perfect place to stay if you are travelling alone. She and her partner are really nice hosts. I spent a great weekend in Paris walking all around with their suggestions.
The department is close to Sacré Coeur and is well connected through the Metro to the whole city.
The neighbourhood is conformed with a mix of local and inmigrants habitants wich makes it really interesting to experience, and allowed me to see a complementary face of Paris, that I never saw before.
I strongly recomend Valentina´s house ( and off course Valentina and her partner) as a great place to stay.
