I visit Barcelona frequently as I simply adore the city. I almost always stay in a different apartment so I can try out a different part of the city.
As I'd never stayed too close to Sagrada Familia before, my partner and I chose this place as it was available and the price was great.
We were absolutely not disappointed. Jose met us at the apartment as agreed, took us through all of the essentials for the apartment, offered us advice on where to go etc and when there was a slight issue with the cooker, had it fixed immediately at our convenience.
I'd very highly recommend this apartment for your stay in Barcelona. The location is great, stylish, clean, friendly and overall a joy to stay in, especially for a couple.
