Pedro was wonderful host. The only downside was that he doesn't speak in English and we don't speak in Spanish but in a way we understood each other :) we needed a iron and he immediately arranged/purchased one and brought to the flat. The apartment on the other hand is quite close to the centre, walking distance to Sagra da Familia and transportation options such as bus, subway.
On the flat, be careful with the shower. the water is leaking all the way under the bathroom door if you don't position the shower head well or take precautions like throwing a towel as a barrier. Otherwise the flat is small but in a quite nice place to have a short time in the city.
