Benjamin was wonderful! He explained everything in his apartment, was very welcoming and accommodating. The apartment was beautiful, quiet at night, though there was construction in the mornings, and we were provided with everything we needed. I would absolutely recommend staying here.
There is no wifi. Major downside but manageable because everywhere else in Barcelona has wifi. The hot water heater is a little difficult to turn on. The apartment is a little far from the center, but with the wonderful metro network that is no big deal.
