The location of the apartment is perfect, a short walk to shops, breakfast spots, the Bosphorus, the public transport and some of the best clubs in the city.
We were three people staying for three nights in the apartment and we did encounter some issues - there wasn't any cold water in the sinks, so if you want to wash your face or teeth you have to use the shower; there was some kind of smell (gas or mold) in the kitchen and the bathroom; there was only one small roll of toilet paper; the linens didn't feel extra fresh. One night we left our umbrella outside the apartment door to dry and it was missing the next morning. We never found it.
Beliz is very responsive to messages and her English is good enough.
Despite the negatives, it is still a good value for money.
