Do you have a recommendation of where to stay in Barcelona? My friend has not made a reservation yet! Thanks!
I usually book rooms through either booking.com or roomsnet.com; they both offer guest reviews of the hotels that they list.
Check out expedia.com or hotels.com. Having traveled in Europe for several years now, I've found that hotels that are rated 3-stars in Europe can fall under the 2-star category of U.S. hotels. However, even if one chooses a 4-star hotel in Europe, you do need to consider the location. For Barcelona, I personally think that the Eixample district would be a good choice.
Thanks again for your comments. Helen found someone from "couch-surfing" just outside Barcelona that she will be able to stay with. She has had "good" success using this website. I'm not sure if I would use it as you don't know who the people are but....I do know a person in Bath, England that open their home through this website with no problems. Interesting concept.
You can also check out www.barcelonaman.com or wwwmadridman.com. These are a couple of sites that are maintained by an expat from Ohio who moved to Spain. He has links to dozens and dozens of places to stay.
