I stayed at Lorenzo and Cristina’s with a friend and colleague, in occasion of a conference in Barcelona.
The location is great, just next to the Sagrada Familia and at walking distance from the other main tourist attractions in the city. If you don’t feel like walking, the metro is literally across the road from the BnB, and everything is a 10-15 minutes metro ride.
The room itself is spacious and clean, with everything you need including not just air conditioner and wi-fi, but also iron, hairdryer and coffee machine.
The manager was really helpful and available anytime :)
Highly recommended for your stay in Barcelona.
