First, the rental quality is more than it looked on the description. The studio is really lovely, within a kind of art deco building. A very charming private terrace, very quiet. The inside was super clean, very well equiped, and the deco is really nice, I felt at home. Very easy to access , very close to some metro stations. Going to MWC, for instance, or airport, is really easy. All commodities around : nice local supermarket (with bio products, and good wines) next door, nice and affordable restaurants around. Last but not least, it's also easy to connect (walking distance) to touristic paths like going by feet to Sagrada Familia, enjoying pedestrian streets full of life.
Second, Vivian brings lot of attention in details and has been very reactive when I whatsapped her for some advises regarding restaurants. She's full of attention, sharp in timing.
In a nutshell, you'll enjoy, it's a real and authentic 5 stars (*****) on all aspects !
