Fantastic location in a fantastic city
Not in the most touristy location, it is in more of a real neighborhood called Gràcia. 5 minute walk to a metro station (Fontana - L3) that is the best line for easy access to all the major sites. Also 6 minute walk to another metro station with more access (Joanic - L4)
Lots of restaurant options in the area too, we tried several and they were great including Gatamala and Taverna el Glop.
Host has great communication and met us to let us in and get us settled. He also helped arrange a big taxi to take us and our bags to the airport after our stay. Some minor inconveniences like the washing machine not working but the owner was very responsive and easy to contact. Temperature very comfortable with AC throughout even on hot days. Kitchen well stocked and there is a good large convenience store literally next door with anything you need. Located on a quiet car-free street and on the first floor, very easy access with lots of bags.
Bunk bed might be difficult for adult to use but just fine for our teens.
