I would like to share my experience, telling you clearly that it is not the best location as it is a dangerous neighborhood. Niche of thieves in Barcelona. Information received at the airport. The apartment is clean but not luxurious. Fantastic, I couldn't call it fantastic. The sheets have been washed but not even ironed. Comparing already in Barcelona, ​​in a 4 star hotel I could stay for 106 euros (double room) per night.
The private bedroom is very noisy, you can hear the noise from the street.
I do not recommend this accommodation to anyone, because it is a permanent risk to travel in this neighborhood. It may be close to the Ramblas, but transit is a constant risk. Sorry for the owner but is true..
