We took the Aerobus from airport to Placa Espanya and from there a taxi to apt. The taxi driver didn't know where it was and went round the neighbourhood and it costs us 7 euros which should only be a couple of euros. It was easy enough to get the metro as Poble Sac station is only a stop away. We have walked to Placa Espanya a few times from the apartment and it only took us 15 or 20 mins.
The apartment is very central and very easy to get to all the main attractions.
The flat itself is cozy and have all your basic amenities. The deco is basic and if bed is all you need then its enough.
Iga is not based in Barcelona but she was always at hand when we needed her help. There were some issues regarding the apartment in the beginning but everything were resolved straight away.
Iga also has a good neighbour who helped us booked our taxi because we can't converse in Spanish.
