Anna was a very lovely host, helped me with a late check-in and there were no issues with the check-out. Instantly sent me locations for the grocery shops and explained where the metro and other transportation is and gave me lots of local tips for other places.
The apartment itself is easy to find, simple but you have everything you need there. Placa Catalunya which is the main square in the city centre is about 7 metro stops away, which is about 15mins.
A massive thanks to Anna and her lovely little daughter for the great time I had in Barcelona :)
