The accommodation situation in Bordeaux isn’t too bad - as a tourist destination in its own right there are plenty of hotels in the city centre, with the usual chains like Ibis and Sofitel to smaller-scale boutique options, and a newly opened youth hostel (Auberge de Jeunesse) near the train station. Being in the heart of wine country, the areas around the city are also well served by B&Bs, campsites and up-scale chateaux for those with a bit more cash to splash.
That said, there are some countries with large travelling support expected, none more so than Wales and Ireland, so around the group stages it could prove tricky to find a hotel room at a reasonable rate if you haven’t booked in advance.
You’ll find a comprehensive list of the major hotels on the Bordeaux Tourism website (http://www.bordeaux-tourism.co.uk/), and the major booking sites like Booking.com and Airbnb.com are popular routes in to finding a room or two. Most of the tourist-oriented hotels are located at the southern end of the city, by the train station, but for the tournament you’ll be lucky finding a room around a matchday for less than £100 a night.
Uefa also has an official accommodation partner - HomeAway (www.homeaway.co.uk/euro2016/) which works on a similar basis to Airbnb, offering flats, apartments and houses in and around host cities. Their search function splits properties between each host city, making it easy to use.
