The flat is very clean ,it was of us but flat is big enough for 4 people .
20 mins walk to Taksim or Istiklal Street but I would not suggest the flat for elder or people with difficulty as the area is very congested with a lot of up hill and down hill which is common in Taksim Square area .
In another note I have to say the Internet connection was big issue for us ,3 days out 7 days we did not have net or the connection was not consistent so we had to go all the way to Taksim to use Ibb(free access to Internet)furthermore the flat is in historic part of Taksim ,been renovated and upgraded it but the ceiling and flat is not sound proof so there will be another move and noise coming from upper floor which can be difficult at night.
overall I would say the flat was very clean, specious toilet and shower and comfortable bed .
