The apartment is really a great option for a group of 6. With 3 bedrooms and 2 bathrooms you have everything you need. Very stylish apartment with all appliances you need.
The rooftop terrace is also really nice and with a view of the Sagrada Familia. We could check in early and Jesus was very accommodating, providing everything we needed. Would definitely stay here again.
Minor thing that the AC is not that strong and with summer temperatures of Barcelona it can be a bit hot to sleep under the covers. But not a real dealbreaker.
