Very nice and unique hotel located right in city center.
Within walking distance of all tourist sights, but there is all kinds of transportation options readily available (Metro, Trolleys, Taxis, Buses, etc.)
Central Railway Station is only a couple of blocks away, if you want to take a train from/to the airport. Taxi will set you back around 45 Euro.
Plenty of restaurants and bars for blocks around the hotel.
The rooms are very nice. It took me a while to figure out all the lights and power plugs, but once I did it, it was nice to have all the options.
My only (If minor) issue, was the shower. I like my showers hot, but water was only warm at best (Not cold, so acceptable). Also there is no shower door, so there will be a lot of water splashed all over. I guess they expect that because there are two drains. If you have mobility issues, you may have problems getting into the shower (Actually a very tall bathtub). And even though that deep tub looked tempting, the water temperature made me think otherwise.
Nice and quiet. I had a great night sleep the nights I was there. I would definitely stay there again.
