We were checked in by Alex's wife Gema as Alex was out of town. We landed in Barcelona early but they were more than happy to let us check in straight away. Gema was very helpful, showing Bec and I round the apartment, where the closest supermarkets were and advising us on some things to do in the city. The apartment was very clean and comfortable and had everything we needed. The shower did leak a little bit but wasn't a big issue. All n all we loved our stay in the apartment and loved Barcelona.
Thanks Alex and Gema.
