first of all the location is perfect near to all transportations (tram fery funicular bus) small studio perfect for 2 people, warm, cozy and clean , there are constructions next door but that's not a problem for us because we go out all day and we come back at night, the host was very clear about instructions we arrived at 2a.m and it was very easy for us to access, and he responded really quick to all our msgs.
I highly recommend this studio and if we come back to Istanbul some day it will be our first choice.
