Negative Reviews


Problems with showers.

Some guests report that they had some issues with the showers and the temperature. The showers did not reach a warm temperature, let alone hot. They either had to wait ten minutes for warm water or it didn't come on at all.


Breakfast is a disappointment.

A few guests state that the breakfast service was awful and offered no variety. They feel that the hotel overcharges for breakfast and it seems as though they use the cheapest cuts of meat and eggs.


No Wi-Fi whatsoever.

Guests report that this hotel doesn't provide any Wi-Fi Internet access to its guests and there isn't even a public spot Internet spot within the hotel for guests to use. Some guests found this upsetting as they would have wanted to connect with friends and family while staying here.
