Great location in Barcelona. Was near the metro station and Plaza Catalunya which is at the edge of the Gothic quarter. Nice view of the city from the window.
Entry door was a little tough to find as the address is #16, but that number is not anywhere on the building, and the door is actually on the other side of the Zara store on Gran Via de les Corts Catalanes instead of Passeig de Gràcia.
Entry lock was confusing with the entry door lock app. Hopefully they update their check-in instructions to say type in 18 and the bell key before swiping. 18 in the intercom code for appt 4-3.
Wifi check-in instructions were wrong. Just scan the QR code on the wifi modem instead of following their instructions.
