Aaaamazing appartments!
Me and my girlfriend with daughter was in three different places in Istanbul, all in the same price category.. and this appartments is best of them without any doubts.
Yes, there is not very easy to access because the downstairs… (it can be dangerous for little kids and nearly impossible for elderly peoples..) but in our case (two 30+ years adults + 4 years child) this was pretty fun and ok in general.
Especially want to point that the appartments very nicely equipped with different stuff : coffee machine, tea machine, microwave, etc etc…
And the panoramic view on Bosphorus is gorgeous!
