We stayed at Jelena's for a month while working from home and had an amazing stay!
The apartment really looks like the pictures, it is nicely decorated and SUPER well located (just a few minutes from Istiklal caddesi).
Jelena was lovely and responded very quickly to any questions we had.
The only minor flaw was that the apartment is on the ground floor and while being very well secured, it was not very luminous.
A part from that, we recommend the place 100% and we will come back !
