The stay was generally OK, but this is definitely not a 4-star hotel.
* The service was not particularly friendly (with a few exceptions, the breakfast service people were very friendly)
* The room was cramped and with a view to a wall with some mural on it, which meant it was always dark even in the middle of the day.
* No kettle by default - one was provided when asked, but it hadn't been decalcified since ever.
* There seems to be a major lack of maintenance, the walls etc seems to be quite dated
* The room was clean and the bed was comfortable
* The breakfast was pretty basic, but was fine for 15€
* There's no restaurant or bar or lobby
* The wifi is pretty slow
* It's centrally located, which is very nice
We also noted in Google Maps, which is not present in _any_ review here on hotels.com, that there apparently are MULTIPLE INSTANCES OF THEFT that has happened at this hotel, and where the responses are from the hotel management, to put it mildly, very nonchalant. Luckily for us, we had no valuables to steal but if we had known this beforehand we would have _never_ reserved a room at this place.
All in all, apart from the thieving, this would have been a very good 3* hotel, but I have no idea why this is rated as a 4* hotel.
