Merce is a very pleasant host. Answered all our inquiries prior to our visit rapidly and offered to help with anything we needed. The apartment was clean, located in a great area (Sagrada familia), and (one of my favorite features) had a big common area with couches and dining tables where it was nice to have some downtime. Ideal for a group of friends visiting the city.
I highly recommend staying here both for a weekend or a week visit.
