Honestly, the worst staying in my life.
This experience was totally awful.
First, they made me go to another hotel, which was supposedly from the same owners, but it was totally different than the description. In this hotel, there was no reception, and no telephone, so every problem that came up (which were too many), I had to walk a square to be attended;
There was no air conditioner control, and the room was heating, I told them, and they just replied with a mean behavior that I had to open the windows, because they did not have it.
Afterwards, I realized there was no hot water in the shower, so I had to shower with cold water, as I did not wanted to go again walking one street just to tell them. Then, as soon as I wanted to use my computer with the so promised wifi, guess what? There was no wifi. The next morning, I went for my free breakfast, which was only coffee, water and bread, and later on I told the receptionist the water and wifi problem; he told me he will fix it, but when I arrived at night, I found out that nothing was fixed. When I walked again to the reception, he started yelling at me that he did not know what the problem was, and that I had to get used to that problems until they found out how to solve them. Not to make the story long, I stayed three nights, and at my departure in the 4th day, there was no wifi, and no hot water.
I would never stay again, even if it was free. Make yourself a favor, and do not ever book in this hotel.
