The hotel is a common 4 stars from the first appearance but it hides dirtiness and inefficiency. I stayed 2 nights there and I had fear of making a shower. The water coming out from the tubes was of a yellow colour. I have discovered this when trying to fill in the bathtub, and then I have discovered that sand or rust was floating into the water. When the water flew out the sand was depositing on the bottom of the bathtub and clearly visible and touchable. I have told twice to the receptionist in two different moments. I have even shown to the second one who confirmed the problem. The second receptionist kindly offered me a breakfast for free but I told him that I wanted a shower. The hotel was full so they could not offer me another room, so I stayed without a clean shower and I could not brush my teeth. Except from the kind receptionist I was not contacted by anyone from the hotel for excuse or a compensation.
Furthermore the power plug of the bathroom (the only one close to a mirror) was not working with my electric razor. I had to ask for an extension cable, which was even a bit broken with open wires, but at least worked.
Another hidden aspect is the stairs which are very small, dangerous, dirty of dust and painting such as a construction stair.
