Location - couldn’t ask for more. 15 minutes from the train station. 25 min from airport. L1/L2 is steps away from Sonder. Catalunya stop with more trains is about 5 min walk. For the futbol fans - Camp Nou is about 20 minutes via train with one transfer or 50 minute walk which we did post game.
Building - nice restaurant with views on top - recommend eating there at least once. Elevators work fine.
Room - nice bed, shower, with balcony views of plaza area and good air flow. Only wish we had a mini fridge. Solis wifi / internet connection - no issues
Leave a tag outside the room for room service - changing towels and sheets.
Easy check in/out process.
Bottom line. When I come back to Barcelona, I am staying here again!
