What a ripoff! My daughter and I booked Hotel Ziel through "booking.com" for a 4 night stay. Shortly after booking we realized we would have liked to rent a car and spend one night of our brief visit to Germany in another City. My daughter contacted both the hotel and booking.com 5 days in advance of our arrival to change the booking. We found out that the fine print says that the entire 300 Euro booking is unchangeable, non-refundable (unless it is 45 days in advance). Who ever heard of such a thing? This wasn't some deeply discounted price or special deal. I have never heard of not being able to cancel a hotel booking with more than 24 hours notice. I will never use booking.com again and advise others to avoid it.

We chose this hotel because it advertized "free parking" and also because of the location, and reviews. Parking in Frankfurt can be 15 to 20 euros per day. Upon arrival, the parking lot held only 6 spaces, and street construction did not permit access to the entire parking lot. The young receptionist woman shrugged her shoulders, and was not helpful. I repeated several times that I booked this hotel because it advertizes free parking. She asked what I expected her to do. I said, "provide free parking, or pay for me to park someplace." I was angry, but did not curse, did not call names. My tone, though indicated I was angry. The receptionist said, "You don't talk to people like this" and she went inside. I drove around for 45 minutes, tried to park on the street, lost 4 euros, and eventually came back and the woman told me to park behind two cars in her lot and block them in. Had I been verbally abusive, I would have understood her behavior. However, I was appropriately angry that she initially did nothing to help and felt no obligation to provide parking.
The room was large, clean, except for mold or fungus growing in the tile of the shower. The breakfast was good. I would neve stay here again, though. The woman took no responsibility for the parking situation. She never apologized, thought it inappropriate for me to be upset, and initially did nothing to try to provide me with parking, even though this is what they advertized.

The price per night is pretty cheap. Bathroom - shower room is very small. No extra cost for 3-Bed room, so that is good thing when you have a bigger group.

Just 400 metres from Konstablerwache station at the quiet end of Zeil. Front desk open 24 hours. Plenty of eateries nearby. Well-appointed rooms with high ceilings. Comfortable beds. Nice hot radiator, and the window and door onto the balcony can be opened. Room 13 is the only one with a balcony overlooking the street. Breakfast included in the price (0800-1100 at weekends), with plenty of variety, but bland quality. This end of Zeil is not busy, but the street noise is obtrusive if you're not used to it, despite the double glazing. The city operates noisy mechanised pavement sweepers, even on a Sunday morning! But if you want the convenience of being comfortably located right in the city, this is really the only compromise you'll have to endure.
