MINUSES - READ THEM!!
This experience taught me to read reviews first and choose the apartment later.
Be aware that this apartment is in the basement. If I knew this, I wouldn't have taken it. The main reasons against basement flat is the absence of direct sunlight. I slept in the living room and the sofa is at least 30cm shorter than presented on photos... I am 188cm tall and I could barely sleep there. I slept diagonally. Since I traveled with a female friend, I guess the hosts presumed she was my girlfriend/wife and that we will sleep together so we got new linens for the sofa only the next day after I asked for them. Lessons for the hosts - always ask beforehand, never presume anything. There are a lot of ants and cockroaches. Both sofa and the bed in the bedroom have really old linens on mattresses with small holes on them. Sofa is also super uncomfortable to sleep on.
Now the bathroom. Water is leaking from the glass sides of the shower outside on couple places and that's why couple minutes after showering you can see puddles there. Our solution was to always mop the floors and wear slippers, but this should really be fixed. The faucet on the lavatory is also leaking or better said - spraying everywhere.
All these stuff are basic and could easily have been fixed, but as I see from the reviews, they are long lasting. For this price, we expected more.
THERE WERE PLUSES TOO:
There are some positive things which are the hosts, Furkan and Kaan. They are communicative, helpful and reply to messages quickly. The location is 5 minutes away from Galata tower and metro station and Istikal street is also there. Supermarket across the street was almost always open, there is a pharmacy nearby, washing machine is also almost as new.
