He gets up in the hotel late.
- Er... Where I am? What a hard headache... I shouldn't have drunk up his coffee in the caf yesterday.

...should’ve drunk MINE! T’was not as strong as his😫

Умник! Чё сказать то хотел?

Александр, не подумайте. "Умник" - это было сказано мне

So what does this translation mean, that he climbs up to the hotel?

I guess someone is staying in a hotel and he gets up late when he's there. ¿

In that case, he “gets up late in the hotel”

So I guess the correct translation would be Он встаёт поздно в отеле.

Вот именно - встает, а не поднимается. Даже Ули знает, как это лучше сказать по-русски👍
