Thanks it-ogo!

So if I booked that, then there will not be some stranger in the same room as me?
Like in "Mimino" LOL!

I used a crappy Google translation because I was in a hurry.
Google translated this word to double room, which is what I wanted. (one big bed in a room.)

EDIT: I am falsely accusing Google, it is the English version of the page that is quite poorly translated.

They should have translated it to "twin beds" or something like that, usually meaning 2 slimmer beds, standing apart from each other.

However, when I checked the Russian version it was clear that the translation must be wrong.
