The hotel was ok at first sight, but as we were staying there for 4 nights, flaws begun to annoy us.
The major drawback was bad isolation, so that you could hear noise (trams and traffic) and it was a little bit cold, or draft, while central heating didn't work well. We haven't try to switch the room, because it would take us time that we were planning to spend in the city. They offered us a heater and the room was warmer after that, but as soon as you switch it off, you can feel the draft again.
Daily cleaning of the room was completely ok, but we felt that the carpet stinks and the room needs general cleansing and not just daily maintenance. So, you have to bring your own slippers for the room.
Coffee kettle worked, but you had to hold the button in on position until water boiled, but this is not a big deal.
The bathroom was modern and clean, but the minor drawback is low pressure in the shower and the floor didn't have angle or heating so that the water disappear after you are done with showering.
Breakfast and restaurant were very good. We are also very satisfied with personnel. They were very helpful and nice to us.
