ROBERTSpainPase claro en verano y mal desayuno
Lo único bueno de este hotel es la ubicación, a 50 metros de primera línea de playa.
No tiene aire acondicionado y pasé calor , tampoco me pudieron dar un ventilador, el parking muy estrecho, se tiene que maniobrar…
Lucas JoséArgentinaLa comodidad y amplitud del departamento con balcón con exelente vista al mar, y su ubicación excelente
Falto una jara eléctrica para calentar agua, Pero en general tenía de todo. Parking estrecho

What we’d check for you here
- That the step-free room is actually free on your dates, and whether it is a roll-in shower or a bath, which the listing never says.
- That the desk is staffed when you land, and that the room is held past cut-off.
- 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.
- Whether the rate moves for your dates, and what it includes.
- What the property actually charges at the desk on top of the rate.
Questions about Alda Don Carlos
What time is check-in and check-out at Alda Don Carlos?
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 Alda Don Carlos allow pets?
No — the property states that pets are not allowed.
Is there parking at Alda Don Carlos?
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.
Is breakfast included at Alda Don Carlos?
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 Alda Don Carlos have Wi-Fi?
Yes — internet access is listed among the property's facilities.
Does Alda Don Carlos 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 Alda Don Carlos?
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 Alda Don Carlos?
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.
