My bf and I stayed 4 nights at the new Sonder hotel. It was perfectly located on passeig de gracia, right next to the metro stop and in the heart of shopping and restaurants. I couldn’t have picked a better location as all the sights were walkable or a few stops on the metro. As the hotel only opened a day before we arrived, there was some teething issues such as only one lift working. However we were provided with an early check in and free breakfast for the length of our stay, which was a great bonus. The hotel is brand new and the design is very modern, with all the amenities you need. I definitely would come back and stay again!
