We had a great time in Barcelona! The apartment is clean, cozy and every corner is decorated with love. It is located in a very good quarter. Restaurants, supermarkets, etc. are all reachable withing couple of minutes walk. Big terrace on the roof with a fantastic view is a cherry on top. Elizabeth and her husband are very friendly and hospitable hosts, they welcomed us very warmly and gave us all sorts of tipps around Barcelona.
A tipp from me if you are travelling in winter is to have warm socks or slippers with you as the floor is pretty cold.
