I wouldn't advise placing a portable bed. It might fit in the hallway area but will definitely be tight.
I think there was. It would be a tight fit but it's doable.
I had a King bed room with a balcony. There was also a small sofa and sofa table. If you removed those, then an extra bed could fit. But as other mention, it would probably depend on the room that is available. I suggest you contact the property.
It all depends on the room that you booked or the room the hotel assigns to you. I think the best option would be to give the hotel a call and discuss your needs directly with them.
I stayed in a room with a king bed and a balcony, yes you can put a small twin bed. Most of the rooms are European small but you have to request a bigger room. At the front desk they are good accommodating your request if they are not sold out.
I don't think so, but I had a small room. There might be rooms on the Hilton floors that are bigger
We stayed in a room with two double beds and there was no room for additional beds.
I had a large King bedded room with a full size sofa. There was probably still room for an extra bed.
No not possible rooms are not big enough for that, go to 1 of the other hiltons in town
