We arrived to the mension around 11:00 pm. We were looking for a bottle of water to take a medicine. Good thing that some bars were open, I was able to buy a bottle of water.
After spending on night both of us felt headache, dizziness, weakness, vomiting, and confusion. But we were able to go on walking tour.
Next day we had to cancel all our tours because of our health condition. That was the same symptoms for both of us. I called the host to see if we can have a late checkout because we can not go anywhere and our bus was living in the evening. They told us that we need to make a new reservation, which I did.
In Madrid we stayed at the beautiful hotel and for extended checkout they charged us only 40 euros, here we had to pay 125.00 euros, initially we paid $90.00. On their reservation page they promised complementary drink. I don't think I have to explain there was no drinks, no water.
Our condition was getting worst. I opened a window and felt that we are brithing with air with carbon monoxide elevated level. With open window it was much better to breathe, but outside was very loud. Level of noise owith open window was around 48 decibels, because this square has 8 or 9 beautiful restaurants on the first floor. Locals are coming all day long to have a drink and food.
I don't know that Is wrong with that room where we stayed, but I have a very strong suspicion that combustion from the restaurant kitchen appliances bellow our room is producing carbon monoxide.
