We could also warmly recommend Alberts appartment. He provided us a good description to his appartment und their we met his Sister. She gave us a warm welcome,showed and explained us everything we want to know. It was clean and everything was like described.
The appartment is great located, 7-10 minutes, far away from the city beach. To go there, we went to Rambla Poblenou and get inspired by all the bars, restaurant and little botiques. The centre of Barcelona is only 4/5 metro stations away from Poblenou. This part of the city is extremly good to relax and combine city trips, visits of museums, shopping, far away from stressing tourism and relaxing at the beach.
Maybe we will come back again for a few more days:)
Thanks again Albert
