One of the best host I have seen. He welcomed us with all necessary information. In fact our train was late but he waited for 45 minutes for us to take with him to his home. He dropped us to the airport as well in his car.
The host provides all the necessary information about the connections to city by metro and about nearby locations. The place is 3-5 min away from metro station where you will find routes to the center. The rooms were clean and had comfortable bed. The bedroom did not have any lock. If you are not concerned about any privacy issues the place is perfect within affordable price in Barcelona.
