I'd recommend Flor's apartment. I was in Barcelona for 1 day and wish I'd stayed longer there. Perfect location in Las Ramblas in the middle of everything and two minute walking distance from Metro. I read previous reviews and it said the neighborhood was loud at night however I didn't hear the crowd only the trashmen. The room was welcoming, clean and had a fan if you get hot. We were able to check in 30 mins early. Our apt area was clean as well. Flor was very helpful to provide maps and routes to get to the apt. She does work very long hours so be patient (unlike me) to get a response on initial email it was within 24hrs after that immediate responses. Flor was very hospitable and welcoming although there was a language barrier everything went smoothly.
