"The Citadines Danube has spacious and well-decorated rooms, and it's only two stops from the VIC (conference centre), and on a direct metro line into the centre. Citadines is basically an apart-hotel, so there's also a kitchenette. Three things: the studio and executive studio are basically the same except that executive studio is on a higher floor, has a coffee machine, and costs more. Second, the hotel only cleans room once a week. You want it cleaned more than that, you pay about 25 euros, which I think is ludicrous as the trash def needs to be taken out more than once a week if you're using the kitchenette. Third, reception could not be less interested in guests coming in. They weren't unfriendly, just very disinterested. Maybe that's because there are a lot of flight crews in the hotel and so they are used to people coming in for a night or for very short days. So, if you're coming in for a conference and hotels closer to the VIC are full, and you're happy to have a very anonymous experience, this hotel is fine. If you want a friendlier hotel with more amenities, I'd choose elsewhere."
