Firstly, Lyonel is a generous and helpful host who went to great lengths to make us feel welcome.
The flat itself is stylish and has everything you need to feey comfortable, including AC and a small verdant balcony.
The neighborhood, Polbe Sec, despite being interesting and central, doesn't get many tourists, so you feel like you're in a real part of Barcelona. That said, there are lots of very good bars, restaurants and useful shops. We walked everywhere, but there are plenty of transport options.
HIGHLY RECOMMENDED!
