Irene is a perfect host! We did not meet in person, but she was very responsive, we never waited more than 10 minutes for a reply, and she always helped us, no matter if it was about recommending restaurants or ordering us a taxi for our departure. We were welcomed by Irene's father, who was also very nice and explained everything about the appartment.
The appartment is great, very clean, you have everything you need in the kitchen and the terrace is something you will love. We have spent every morning and evening there. You have to climb many stairs but it is worth it!
The neighbourhood is great, you will not use public transport because everything is in a walking distance. 15 minutes slow walk to the market etc. The street is full with grocery stores open until late and the next street, Carrer de Blai is full with great tapas restaurants.
I can seriously recommend Irene's apartment! :)
