Okay this may be a silly question but I'm going to ask it anyway. I will be in Europe for 5.5 weeks. I want to be able to book some airbnb locations once I'm in Europe because I'm not set on where I will be when. That said, when I go onto the airbnb site will I be able to book hotels, transportation etc as though I'm booking from Canada? Like, will it automatically be payable only in Euros? I know when I have travelled previously for example I can't use Netflix in the Caribbean although I have an account because it doesn't recognize it from the location. Hope my question makes sense.

Yeah.. the airbnb website is accessible whereever. Netflix doesn't work because it has regional restrictions and isn't offered in the Carribean.

Will show prices in whatever currency yu want.... Did it while I was there

We used easytobook.com and it was the same as using from home. In Barcelona we wanted to extend our stay but the hotel wanted a higher rate. They let me log on through their computer and book it at the lesser rate

As long as you're at airbnb.ca (emphasis on the .ca) - you will be paying in $CAD when you book, just like you would at home. I think once you log in, and make any sort of search, you are actually redirected to the Canadian 'version' of airbnb (airbnb.ca), no matter what, even if you start your search at, say, airbnb.co.uk
All of the different country 'versions' of the airbnb site (airbnb.com in the US, airbnb.co.uk in the UK, etc, etc) have the same listings, and the prices are actually identical, they're just being automatically converted into your currency for display.

Any suggestions for accommodations from anyone? Portugal, Spain, France Italy

Barcelona we stayed at Hotel Praktik Garden,
Carrer de la Diputació, 325, 08009 Barcelona. It is definitely not fancy but had a comfortable bed, was clean and the staff were friendly and helpful. Only a few blocks from the main square, we took the bus from the airport and walked to the hotel. It was quite reasonably priced via Easytobook.com. They don't have a restaurant but do offer a breakfast package. There are lots of restaurants in the area.

I can't really recommend any airbnbs as it sounds like you have a car. Make sure that the places you book on airbnb have access to parking. The best places to stay generally are in the city centre where parking is scarce or expensive.

In Italy I stayed in the most perfect air bnb house in Florence... If you want info just pm me

I will only have a car for the Algarve and to get me u to Seville.

Where would I find apartments for 5 day stints Don?

Diane, in Amsterdam we rented apartments for 2-5 days through the link I posted above. We found a lovely one in Brugges Belgium for 5 days that was phenomenal and cheaper than the hotel we left in Holland on or way there.
