The location of the flat is perfect for a city trip. Montmartre offers all you want for a nice dinner and a drink afterwards and you are not far away from the main sights. The flat isn't very spacious but we, three adults, managed very well over our four days trip.
I really liked the style of the flat which was a mixture of treasures from the flea market and modern furniture.
The communication with Paulina was unproblematic and easy. Although we didn't meet in person, I knew I could reach her, if there would have been a problem.
