Great location within walking distance of many Barcelona locations, and very close to the metro for anything further away.
From the airport I simply took the Aerobus to Placa Espanya, and although you can then take a bus or metro it is only 10-15 minutes walk down Ave Parallel, which was a nice chance to stretch my legs after wearing a mask at the airports, flight and bus for a few hours.
The apartment was easy to find and checkin was straight forward. We actually didn't spend much time in the apartment since there is so much to do in the area and around Barcelona!!
There are lots of cafes and restaurants very close by on Carrer de Blai (one minutes walk from the apartment back towards Parallel), and we also enjoyed a couple of cafes/bars on Plaça del Sortidor square (a couple of minutes away at the end of street). There are also lots of supermarkets close by, and the large Mercat de Sant Antoni is only a 5 minute walk.
