Positives: good location, clean rooms, nice personnel, decent breakfast.
Flaws: Rooms are tiny - for Europeans it is enough, but for American tourists it will be too small.
We were staying on the 4th floor at the attic, and we had an information on the skylight window "do not open unless the fire hazard". The ventilation is however very poor, so after taking a shower, the bathroom and whole room were like sauna.
We had 2 single beds instead of one double. Single like I have not seen since I was 6 yo.Even if the width of the bed was a standard 80 cm, the top mattress was much narrower, and there was big hole between beds, so hugging is out of question.
The bathroom is decent size, although requires some acrobatic skills to close the door when inside. Generally clean, however there were black trails (of possibly fungus) 10 cm over the floor in a shower area. The shower is a disaster - the floor in the shower is not correctly shaped, so the water spreads in entire bathroom. There is no way to regulate water temperature - it is either cold or hot, even if you regulated it and then did not touch the taps. Drainage in the sink does not have the strainer, so if your jewelry falls into sink, forget about getting it back.
After I have posted my review on tripadvisor, the hotel responded that the room was "economy" type, so maybe other rooms are better.
