Maria Luisa's apt is exactly if not better than described. We were 2 couples and the apartment was perfect for us. It is super clean and tidy with plenty of everything you need for a city break. The kitchen is excellently equipped, the roof terrace is great for the sun and a cold one or two, super clean and location is great being just 5 min walk to P Espanya and the metro.
Would defiantly recommend and next time we are in Barcelona we will look no further.
ML is also a great host who very enthusiastically gave us lots of pointers and took the time to explain how everything works.
