Mercure Firenze Centro in Florence

Location is great, near train station, but everything else is not up to standard. Do not recommend this hotel at all. How is this a 4 star hotel? It should just be a 2 star or 3 star hotel. The rooms were run down, air conditioner not working, it was so warm at night! Complained to the staff but they insist that there is nothing wrong with their air-conditioner. We experienced blackout one of the night, and have to call the front desk for help. Took them more than 30 mins to resolve it and they still expect me to pay for the night stay. Toilet door cannot be closed properly, there is only 1 bottle of 2-in-1 shampoo and shower foam in the toilet. No hair conditioner, no toothbrush provided. The rack in the toilet was slanted down and I couldn't put my facial form on it as it kept dropping down because its slanting down. Housekeeping was horrible, they didn't even replace my paper cups meant for brushing teeth. Tissue papers were also not replenished. Bottled water provided in the room was not free and they didn't indicate nor inform beforehand. I was asked to pay additional 9 euros when I checked out of the hotel. Do not recommend this hotel. How is this even a 4 star hotel rated by others?! Ridiculous hotel and service.
