Koni’s place is really well located. Near pl. Catalunya you have everything you need and almost everything is walkable. Restaurants and shops near are also really convenient. The place itself looks a bit overused from previous bookings but it is something expected for the location! Also it’s really convenient for the transport to the airport with aerobus. Lockers for your suitcase are nearby.
Recommend it to have an easy stay in the centre of Barcelona.
