Perfect directions that greatly simplified the trip between the airport and the apartment (I'm embarrassed to say I've been going to Barcelona for years and never used this bus system!). Extremely warm welcome upon arrival. Apartment was perfectly clean and perfectly matched pictures and description. Great location, calm relaxing but very close to more lively parts of town. Our host even had a map with all important locations highlighted for us (tram stops/bus stops/super markets, etc). They even went shopping for us and filled the fridge with basics such as milk an toast! Finally they were even flexible with our checkout time, which was greatly appreciated.
10/10 would recommend/will be back!
