Questions about On 320 Apartment
What time is check-in and check-out at On 320 Apartment?
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 On 320 Apartment allow pets?
No — the property states that pets are not allowed.
Is there parking at On 320 Apartment?
Yes — the property states that parking on site is free. Whether a space can be reserved in advance varies, so we check it against your dates.
Does On 320 Apartment have a pool?
Yes — a pool is listed among the property's facilities. Seasonal closures are common, so we'll confirm it's open for your dates.
Does On 320 Apartment have Wi-Fi?
Yes — internet access is listed among the property's facilities.
Can I book a block of rooms at On 320 Apartment?
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.
Does On 320 Apartment 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.
How do I book On 320 Apartment?
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.
