Very nice flat and great experience with Koni. The host was very responsive and gave clear instructions for finding the apartment. Everything was done with access codes, so it wasn't necessary to meet with the host in order to obtain a key and enter the building, which was much more convenient for me. The apartment itself was great; charming design and furnishing, clean (emphasis on clean), modern amenities, nice bed, and overall very comfortable. The apartment I stayed in is ideal for a couple looking for a romantic retreat in beautiful Barcelona. Highly recommend.
