Ewa and Pau have both been great hosts. Upon our arrival they gave us a lot of tips about the neighbourhood and Barcelona overall. The communication with them was perfect and any kind of problem got resolved almost immediately.
As for the apartment it is clean and cozy and looks exactly as in photos and even though it's located right in the center of Barcelona the windows are facing small and very quiet street and you'll have no trouble sleeping at night. There are lots of good supermarkets nearby. The kitchen is equipped with everything you might need to cook at home. We had a wonderful time at Ewa & Pau's place and highly recommend it to anyone!
