The apartment looks exactly like the photos and all the descriptions are correct. The location is great, very close to the metro and easy to go anywhere. Very safe at night as well.
Alex was already waiting for us when we arrived and spent a good amount of time explaining everything we need to know, e.g. tourist spots, supermarkets, bread stores, etc. Very useful for us. He even prepared some water, orange juice in the fridge. The apt got everything you need if you decide to dine in. There are also many materials related to BCN and their artists for some reading.
All in all, we love the apt and the experience staying there. If I am in Barcelona again, I will definitely choose to stay there again!
