We were a small group of three friends staying here.Cristina was a really great host! She was super quick with her responses from the very beginning, and made sure we were happy with everything after the check in. She basically walked us through the map of Barcelona, and gave us excellent recommendations for restaurants, shopping and tourist locations to visit.
The apartment is in a very good location in Gracia. Both the L3 and L4 metro lines (city center access) are 5-10 minutes walk away, and Bus 39 (bus to the beach area) stops just 1 minute away. There is both a supermarket and a fruit / veg shop on the corner, and plenty of nice local cafes and restaurants within a few minutes walk away. The apartment itself was clean, cosy, quiet, and well equipped. I can only recommend!
