Just what you need for a city break, not too fancy but also clean and well equipped
No issues throughout our stay. Tram line right outside with regular transport links to the centre. Not in a very busy area, but nice cafes/breakfast spots open. Beds were a little solid for my liking, but personal…

The worst experience
I stayed at Union Hotel for 7 nights, and it was without a doubt the worst hotel experience I’ve ever had. I cannot comprehend how this hotel is rated as 4 stars because it doesn’t meet even the most basic…

Whether there is room for a pickup, a trailer or a van, not just a car.
Whether breakfast is in the rate or added at checkout, and what time it runs.

Questions about Hotel Union

What time is check-in and check-out at Hotel Union?

Check-in is from 2:00 PM. Check-out is by 12:00 PM. If you're arriving late, tell us and we'll ask the property to hold the room.

Does Hotel Union allow pets?

Yes — the property states that pets are allowed. Size, number and fee are set by the property rather than by us, so say you're bringing a pet when you book and we'll confirm the terms before anything is charged.

Is there parking at Hotel Union?

Parking is listed among the property's facilities. Whether it's free and whether a space can be reserved varies, so we check it against your dates rather than promise it here.

Is breakfast included at Hotel Union?

Breakfast is offered at the property. Whether it's included depends on the rate — the board type is shown on each room once you put your dates in.

Does Hotel Union have Wi-Fi?

Yes — internet access is listed among the property's facilities.

Does Hotel Union have wheelchair accessible rooms?

The property lists step-free or accessible facilities. That flag is the one least able to settle the question: a hotel can carry it and still have a step at the entrance, or a bath rather than a roll-in shower, and it does not say whether the accessible room is free on your dates. Tell us what you need and we'll ask the property directly rather than reading you the flag.

Can I check in late at Hotel Union?

The property lists a front desk staffed 24 hours, so a late arrival should be possible. Standard check-in is from 2:00 PM. Rooms are still released after a cut-off at some properties regardless of the desk hours, so tell us your arrival time and we'll have them hold it.

How do I book Hotel Union?

Put your dates in above and book online, or call (888) 789-8585 and we'll do it for you — including things a booking form can't handle, like a block of rooms, a monthly rate or an invoice for your employer.
