This is a very small hotel, so one should expect a quaintness and lack of services. The Art Hotel goes some way to that expectation. They do not offer credit card payments (as the previous post says) but they rely on the literally next door cash machine for that. They offer a wireless connection in the room but that didn't work and the night manager couldn't hope to fix it. They don't offer breakfast at a time relevant to anyone with a day full of tasks, but they don't mind if you help yourself to a bottle of water from the fridge instead.
The decor is not necessarily arty at all-it's the post-communist nouveau-riche's idea of what art should be like: lots of frills and decorative twists, but the rooms are spacious and the showers are good.
Overall a much better experience than other three-star establishments may have offered and its centrality beats it all, but not easily anyone's favourite hotel.
