Our experience at Esther's apartment was amazing! The terrace has the most amazing view and we were surprised that my friend and I both got a room each. While there was no air conditioning, having the windows and doors open was fine as an alternative. There is about eight flights of stairs to walk up but it is 100% worth it for the location and the actual apartment. Esther was even nice enough to give us a drink when we went down to say goodbye to her on our last day which we drank on the terrace overlooking Barcelona- great way to end our trip! Highly recommend.
