Eduardo is a very precise and welcome host. He gave us all the support we needed prior to our arrival in Barcelona such as supermarket locations, restaurant suggestions, etc.
The house was very clean and well-equipped. The position is perfect, on a beautiful street, big but not noisy and near Plaça de Catalunya where there are many options for public transportation.
Many of the most important things to see are very near such as the Barcelona Cathedral, Sagrada Familia, Casa Batllò, La Rambla, Barceloneta, Santa Maria del Mar, ... all are walking distance or with a short subway ride.
The only thing I was a little disappointed, is that we never met Eduardo in person but aside from this, we were extremely happy with the choice and would recommend staying there!
