Great place overall. Claudio met us at the apartment to walk us through and give us tips on our stay in Barcelona, which was much appreciated. It was in a great, more relaxed part of the city with more local/less-touristy restaurants. There is also many grocery stores and a market nearby for those who like to cook!
The apartment was a great home base, and was very comfortable and clean. Some may find that the bed is too firm, but we didn't mind at all! Also good to note that the hot water tank runs out quickly (it's an old building) so back-to-back showers is a little difficult. All together, we loved our stay and would stay again!
