First of all, the hotel is situated 5 km away from city center. There's no way of walking there.
The room was clean, but the furniture and the tiles and fittings in the bathroom were old.
Even worse, the bath consumables were not changed daily.
The breakfast was of poor quality products and with limited choice (for a 4 star hotel). The breakfast room is very small compared to the number of rooms in the hotel (if you wake up around 9, it's difficult to find an available table).
