I had a great stay at Laila's. She made me feel comfortable from the very beggining, she's got a cool and relaxed attitude and the place was spotless. I was arriving late and she made it super-easy to give me the keys.
The place is lovely (the common areas are on a different floor so I had a lot of privacy). I also got a private terrace, a comfy new bed and loads of sunshine and breeze. The neighbourhood is great for enjoying typical Spanish mediterranean life - laid back bars, tasty tapas, cheap wine & beer everywhere hehe and a historical park just in front of the door, which is rare in Barcelona-.
I could enjoy the busy touristy areas of the city and come back for a siesta and a quiet dinner in the terrace in less than 10-15 min by direct metro, so for me it was a perfect balance.
The area is friendly and not touristy, even though I walked to Parc Güell (a nice panoramic trek crossing three linked parks which starts in front of the appartment). I also walked to Hospital Sant Pau and Sagrada Familia which is quite close.
I really recommend this place for those who want to enjoy Barcelona knowing they'll be able to sleep tight without cars and loud people and who also would like to know real Barcelona life.
