The measurements below were posted a while ago about the jardine sizes for the upper apartment. We're in the Naranjos and they are very similar for us too but I don't have them here.
There's a couple of options you could go with - in the big room if you had no other furniture you could put a camp bed in against the wall as you go in. Probably have very little room to walk around but is possible.
Second option is for the small room. You could run your beds from the window wall towards the windows. This gives a decent space in front of the windows where you could put a camp bed. Again would be tight but possible.
Or you could put the beds the other way and push them up as far as the window witouth a bedside cabinet in between, you could get a camp bed in again in front of the wardrobe.
For our second bedroom we bought platform beds that have a good space underneath and are very light and easy to manouver. You could put the camp bed underneath during the night to make the room more usable durning the day.
The bed bases were from Gina Nevarra - i have a photo of our bedrooms which would show the space, if you are interested pm me and I'll send it to you. Bed bases were cheap which was an advantage!
