Nacho is what an airbnb host should be, and more. He gave way more information (sightseeing, how to get there, prices, food, maps, snacks, etc) than any tourist information center can give. The place is charming. It is on the 2nd floor so carrying a heavy luggage might be a bit tiring but the house is like an IKEA showroom, one that makes you feel at home. Simple yet chic and modern. Toiletries, soft drinks, cookies, electrical sockets, washing machine, hangers, towels are all provided for. 4-6 supermarkets are all within walking distance. Metro and train stations are nearby too.
Location wise it is a bit out of way from city center but Barcelona metro is efficient enough to compensate this.
Thanks for making our Barcelona visit very enjoyable.
