Nadia has very tastefully decorated her apartment. It is charming and cozy. It is a good space for one or two couples to share. She makes communication and the whole drop off/pick up of keys very easy. The apartment is located right in the heart of the city so it is convenient for catching taxis, the subway, and seeing sights. The only drawback is that the alleyway that the apartment is in can be noisy but that's the price you pay to be in the center of it all. I recommend this apartment as a great jumping off point to see what Barcelona has to offer.
