there are 2 beautiful cats, treat them as king and queen and stay there if you love them :-). Mercedes was a great host, waited for me although I was late explained to me everything about Barcelona and helped us plan our stay. She makes great mixes, put for us a fullfilling breakfast!
The location is centralized in the most touristic place in Barcelona and well connected around, great start to see the city.
While the apartment is a bit old with not too much privacy, the pricing is extremely cheap and its in a great place! backpacking with your friends or alone, I'm definitely going to visit Mercedes. And thats for her great hospitality and her beautiful cats.
