Flea-ridden hole in the wall
Besides the terrible location with no parking and along a busy and noisy street, this well-past-its-prime hotel also seems to pride itself on the insects it harbors in its linens. A complaint to the manager on duty elicited little more than a "that can't be...we've never had that problem" (like I could fabricate the red welts all over my body) and a half-hearted offer to change rooms. The rooms and hallways appear to have flooded at some point as the paint is peeling and worn away and the carpet is worn and stained. The room's electric devices (save the TV) are all unplugged, so you spend half an hour climbing behind furniture to plug things in. The room's master switch kills all electricity, so you get to re-set the clock every day, otherwise you sleep in complete darkness with no way to know the time. Breakfast is poor and actually costs 17 euro extra.
If this was ever a 4* hotel, it wasn't any time recently. Avoid at all costs. Holiday Inn should be ashamed.
