The apartment is lovely. Two of the rooms are nice and large (one of which used to be the living room). The 3rd which is the twin is a bit more moderate in size, and feels like a utility room with the dryer in there. Lol.
The apartment was lacking in basic supplies in the kitchen such as oil, sugar etc if you wanted to have a simple breakfast. i would say the kitchen, which is the only communal space, is too small for a party of 6 and is really just suitable if you are not intending to spend much time in the apartment. The table sits 4 plus the bar sits 2.
A bath mat would have been useful for water splashes and wet feet from the shower. As noted by other guests, the shower is super sensitive and either too hot or cold.
The terrace we had a quick look at but it was a bit sad looking and lacking in tlc.
And the 4 flights of stairs is a killer but Oktay was kind enough to help us with this. In fact, he was a great host, very communicative and helpful with advice and all our questions so top marks for this.
