The flat was bigger than expected with 3 bed rooms and a big living room ! Definitively, it is very well located... Supermarket, bakery, restaurant, subway(diagonal) and main touristic points (Casa Mila, Casa Batllo, Sagrada Familia at a walking distance with a 2 years old kid...
The flat was clean (the floor cleanness not perfect for our Japanese standard).
Pilar's husband welcomed us very nicely, accommodating in term of arrival time and even prepare a baby chair!
As others comments already mentioned, the flat seems dedicated for rent/AirBnb so no much things in the kitchen ( sugar missing for example). At least, there were lots of space to put our stuff !
The overall experience is good !
