The apartment is for 2 people OK! But sleeping facilities is disastrous for 3rd and 4th persons.
The answer to "Can you give me another mattress" was: “ thats budget stay you must Understand that ".
The apartment is centrally located, next to it there is a supermarket, the windows are near the main road and therefore very noisy (If the window is open). If it were possible I would look for other options. Because I couldn’t sleep in the night.
