Frédéric's apartment was very clean, and located in short distance to everything such as the metro, both small and large supermarkets and famous sights such as La Sagrada Familia. We wanted to see as much of the city as possible, so we walked basically everywhere, and were surprised that much of the city was maximum a 30-40 minute walk away. We had a very late check-in, but this was no problem, and we really appreciated Fréderic's flexibility regarding check-in time. The day after, we met him at his office and he then provided great tips to what to see or where to eat.
We would absolutely recommend this apartment and Fréderic as a host. He always answers questions within a day and the communication was very good!
