First of all, this is not a 4-star hotel, probably 2, I would say.
The staff was very friendly, the room was clean and was cleaned every day.
The shower was getting filled with water, I reported it to reception and it was fixed the next day.
The minibar did not work at all, the small fridge was broken so the drinks were all the time at room temperature, reported the problem 3 times to reception but it was never fixed/changed...
The location of the hotel is very nice, close to stations and main attractions.
If you can get a good deal for this hotel take it as it is alright, otherwise I would better look somewhere else.
