Second time in my entire life to give 5 stars for every aspect. The house was sparkling clean, when we arrived I noticed they even left us a pouch with laundry detergent for 1 wash (it was extremely helpful as for 1 week of staying there I had a couple items to wash for the kids). They already left us enough dishwashing liquid for a week and a sponge for the dishes, which I usually had to get myself. The view was spectacular. The location also quite outstanding, the metro was right outside the door of the building, and the tapas bar downstairs was the best place to have brunch every single morning, and tapas on the last night in barcelona. The room on the end was indeed a bit noisy, but the good kind of calming street noise, after walking 16 km/day and visiting Barcelona all day, falling asleep with the background noise was not a problem at all. The walls are indeed a bit thinner, but if you're not a loud, obnoxious neighbour that wants to throw parties every night it's not a problem at all. The water pressure was great, I saw people saying you lost hot water after 2 showers, but the 4 of us could comfortably take a long shower each in the evening and the hot water wouldn't run out. The online check in was GREAT and very easy to use and the digital keycard on our phones was perfect, as I didn't worry for the kids, knowing they had the key on them at all times and wouldn't lose it. The second there was a problem for someone whose phone key didn't work, they sent a message to the whole building asking if we had problems too. When I told them that yeah, somtimes it took a couple tries or a phone worked and one didn't, they immediately sent us a physical card to solve the problem. Very quick to respond and solve our inconvenience, even when we just didn't know how to start the thermostat to turn up the heat, they immediately took the time to help us.
