I would visit Barcelona again and definitely stay with Soler family. Every family member is amazingly friendly and would always check with big smile if I was ok with everything, even though it's usually fully booked.
And this beautifully decorated apartment is located on center of Barcelona, so I hardly used public transportation and almost every attract point is just walkable distance from home.
What's more, I wanted to stay with soler family for one more night than I booked, but there's no room available. So Roger even organised my bed at ironing room to sleep for free. Of course you can't expect free room if there is official room available. But i'm writing to let you know how they are helful.
I have had great time in Barcelona and it's worth staying at Roger's.
Muchas gracias :)
