Lisa's flat is located in a very convenient and nice locations literally 5 min walking distance do Sagrada Familia. The flat itself is lovely: the light coming from the window in the living room brightens up the decorated floors and gives the space an Almodovar's movie kind of vibe, which makes you forget the 4 floors of stairs to get there (which are not that hard to walk anyway and are a perfect excuse to stay fit also while on holiday). Lisa herself is wonderful, very quick in replying, always very helpful and she even left us a bottle of Cava in the fridge as a present to fight the heat wave.
Would most definitely come back. Super recommended.
