I stayed one week at Karla's place and I must to say the place covers the basics that a low budget travels looks for. The great things about this place is localization and the low cost compared to high prices of Barcelona in the summer time. The downsides: It has only one bathroom for the 5 rooms of the house; the bathroom was most of the time clean, but sometimes duo to the waiting lines you just have to use the bathroom as it is. When I arrived I had communication issues with Karla and the address was not precise in the Airbnb guide. But outside of that she seems a very attentive host. The people I met while there was amazing.
