We spent a week at this very clean, quiet, vintage apartment. It's in a great location close to Sants train station, restaurants & cafes, and Montjuic...yet was unexpectedly quiet for how central it is. Comfortable bed, very fast wifi, nice balcony.
Jepis & Merce were communicative and responsive, and Xavi was a kind, easy-going guy who checked us in and out on Jepis' behalf, and even came by at 22:30 on a Friday night to help when the toilet stopped flushing (and was fixing the issue more permanently when we left). Good hosts, recommend!
