We had a nice stay at Johanna's place. The apartment is as described and is definately good value for money. The hosts greeted us with special treats and provided useful advice for discovering the city. Not being far from touristic centre it is also located in Bohemian neighborhood of Barcelona and is suited for people who are looking for authentic local experiences. Nevertheless, it should be taken into account that due to the fact that there are many restaurants and bars located in the vicinity, it can be bit loud during weekend nights. Other than that, I would definately recommend staying at Johanna's place.
