The place was gorgeous but they wouldn’t let me pay with my Chime card……. Very disappointing because it’s no different than any other banking debit card.
Las zonas comunes son muy divertidas si vas en familia hay zona de juegos y esta muy bien.
Esta en una zona buena de congresos y oficinas, con metro cercano pero no estás cerca del centro y el shuttle que tienen solo te…
I liked everything.
I didn't like the pillows on the bed, need new ones and I didn't like the breakfast options, other that that everything was great!
Camera molto spaziosa ma asettica. Buon servizio di valet.
La colazione non era quella a buffet e molto restrittiva.
Lots of public space in the main and upper lobbies. Excellent workout room. Very clean in all areas.
Comfortable bed.
Valet and self serve parking are $20/night. No options.

Rates include the taxes and fees we can read.
The property may take a card at check-in for incidentals.
Guests are required to show a photo ID and credit card upon check-in. Please note that all Special Requests are subject to availability and additional charges may apply. A deposit may be required at the property.
Check-in is from 4:00 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.
No — the property states that pets are not allowed.
Yes — parking is available on site at a charge the property sets. We check the rate and whether a space can be reserved against your dates.
Yes — a pool is listed among the property's facilities. Seasonal closures are common, so we'll confirm it's open for your dates.
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.
Yes — internet access is listed among the property's facilities.
The property lists meeting and banquet space, which usually means it handles group business — but how many rooms it will hold at once, for how long, and at what rate are set case by case and are not in any feed. Tell us the dates and the number of rooms and we'll get those terms from the property in writing before anything is charged.
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.
The property lists a front desk staffed 24 hours, so a late arrival should be possible. Standard check-in is from 4:00 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.
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.

Nothing to do with the booking above. The same market, priced the same way, for if this one is not it.
