The flat is great. It is a bit of a hike up (4th floor), but worth the climb. We had a very welcoming check-in, despite our delay (protests in the city!). Everything was clean and in perfect order. Cleverly, the bedrooms are at the back of the flat, which meant it was quiet at night. The front of the flat is not overly noisy (just a bit of traffic), but not disturbing. Very kindly, some breakfast bits were supplied to get us started (tea, coffee, milk, zwieback...). Every night we came back to the beautiful Sagrada Familia - excellent location. We would highly recommend this place!
