I will be in Barcelona for one week from July 15 to July 23 and wanting to spend 70$/day in a hotel or apartment. Any suggestions?
I second Airbnb Online Services Spain S L. During that time, you may not be able to get the whole place for that price, but l bet you could get a nice room. If you are brave, you can wait till the time gets close, and use lastminute.com España to get good deals. We did that on our Barcelona trip and ended up staying Ayre Rosellon Hotel right by the Basílica de la Sagrada Família for €50 per night, and it was awesome. Fantastic place. Happy travels.
