Flor's place is unbeatable! It's literally a minute walk from the Liceu metro station in La Rambla. Very accessible to local public transportation (L3) and the Aerobus to and from BCN Airport. The advertised address will lead you to a main door full of graffiti but don't let that deter you. The main entrance to the house is next door and the apartment is on the 2nd floor up the marble-floor stairs. There's a 24-hour convenient store and ice cream shop right out the alley way on Calle la Boqueria.
Flor is super accommodating. I came in late night and she was up to welcome me and show me how the keys to the doors work. There's a light fixture issue in the bathroom and she also showed me how to navigate that.
Wifi works fast that's why I'm able to write this review while I'm getting ready to check out.
