Nuria's flat is just perfect.
It was very clean, big with huge terrace. You can also find a lot of traveling books. I was staying at her place with my boyfriend and his parents. We were all in love with a view from her gorgeous terrace. We could see people working on Sagrada Familla when drinking our coffee and eating tapas.
If you take a taxi at night from the center it will cost you just 10 euros. By foot it will be maybe around 30 min walking from the coast. It is 2o min walking for the magnificent park. If we could come back we would stay again at Nuria's place. We had great experience and we will recommend this place to all our friends.
