Barcelona Apartment Recommendations?

My husband and I will spend 4 nights in Barcelona in October.
We are looking for a quiet and clean studio, or 1 bedroom apartment, in tourist area, with A/C, fridge for max 65E/night.
Thank you for your help.

I think 65E/night will be difficult to find. I prefer to stay in Apts. as well.

Here is a good site with some options.

The Citadines would be my first choice. Good luck and have a great time!
