This is where lots of business people stay. It's not as luxurious as some of the other hotels in Oxford, but it's definitely got one of the best locations as it's really near the trains and bus stations and the town centre. It's open 24 hours and I think the reception staff speak quite a few languages (some definitely speak French, German, Italian and Spanish). There's Wifi and room service, so great for business travellers, but also useful for tourists who want to stay in a central location. Prices range from £130-£150 for single to triple rooms including breakfast. They also have family rooms. If you're in a group, give them a call as I know people have managed to get group discounts before.
