This place was the best stay of all of the Airbnb I had. The owners were flexible, very kind and the communication went smoothly.
The apartment was super clean, adorable, well equipped, stylish and the rooms are perfectly placed for a bigger group so you can have your own space and also sit together. My favourite was the terrace.
There were more than enough towels and beddings prepared plus the kitchen closet was full of basic things like sugar and coffee what I find practical since I don't like wasting.
The location is good. It's in between Sagrada Familia and Park Güell although it is not in the center if you are an active one you can get anywhere by walking or there is fast access to the bus and tram stations for the lazy ones. :) For those I recommend to buy T10 cause we never used the whole day "Hola Barcelona" ticket more than twice a day.
So all together I can only recommend Frédérique's place without any complaints!
