This apartment has a great location: 10 mins to the Grand Bazaar, 20 mins to Sofia or ferries.
It has all you need for several days: a bed, a kitchen, a bathroom. Nothing to complain about. Yes, you may hear segulls late in the evening but this is some kind of unique experience, haha.
As for the flashing that one of the previous guest mentioned, yes, it is not strong one. Though I am sure that is not something that can ruin your impression from the apartment or Istanbul, in general :)
Saban also helped us to arrange appointment of a nurse on the 1st of January to have a PCR test. Thank you very much for that!
Do not hesitate to book this apartment, you will like it.
