We spent a week beginning of June in this lovely flat situated in one of the nicest streets in Eixample. Location is perfect for exploring Barcelona, walking distance to Place de Catalunya and Passeig de Gracia. Description of host of the apartment is accurate, it is a charming flat with superb floor mosaic and new and clean kitchen and bathroom. One of the sleeping rooms faces the street, so is a bit noisier (although street is semi-pedestrian, so rather quiet), the other faces the back courtyard with the elevator, which can be heard of course but is not disturbing. Furnishing is very basic but functional, although wardrobe in one of the rooms is only for host's use and therefore only some small drawers are available to put in your stuff (we kept clothes in our suitcase and it didn't bother us). There is a spacious terrace which we didn't use because it is one floor upstairs and you'd have to carry all cutlery, but if you take the trouble to do so it must be wonderful in summer.
All in all, we can recommend this place and would stay there again.
