Hello everyone

first and foremost i would like to thank Madridman for running such a great website! it has been very helpful.
and thank all of you guys for participating and inputting all of the responses

Now i would like to ask for your help.
I decided to give myself a graduation college gift and go to Spain with my sister on May 28 - June 9.
We were thinking (let me know if its a good idea) to spend 5 days iN Madrid and the rest in Barcelona...i would like to find a nice hostel with decent looking rooms, preferably not too expensive in both cities. One of the main things is to be in the center of the city, but not to be in the very loud neighborhood.

can you please recommend something?

thanks!

Alexis
