First of all, communication with Tanvir was super easy and he reacted really quickly.
Yet, it would have been a much nicer experience if the bathroom (esp. shower) wasn't full of mold and smelling like chlorine at the same time, the shower wasn't falling apart, the apartment (floor, kitchen, bathroom, toilet) was properly cleaned, the balcony door was working, the main door was secure (you could literally open it with your thumb if you wanted), the wallpaper was not torn down.
This apartment is definitely not in the condition the photos suggest.
Tanvir is a nice person and he did not bother letting us check in early and then being delayed anyways. But if you want to stay in a clean room, I cannot recommend this. Luckily we only slept over for one night, so it was OK.
