I arrived at the apartment building by cab from the Areobus in Catalunya Sq, it costs less than 10 euros. The district is delightful, lots of restaurants and Super Mercats, the latter much smaller than we have at home and the fresh produce was generally better.
Pep was very helpful and answered all my queries. There was a Lonely Planet guide to Barcelona in the apartment when I arrived and it was quite worn when I left. Do try the Vietnamese bakery across the street, very good coffee and cheap. Buy a T10 ticket on the Metro, cost just under 10 euros and saves a lot of problems with ticket purchase. The view from the terrace is 4 star and the hospital, now a university, should be explored, unlike most attractions in Barcelona it lacks crowds.
I can recommend this apartment for the lovely area and handiness to transportation, eating places and Gaudi's unfinished masterpiece just down the avenue.
