We stayed here for a month and can wholeheartedly recommend the apartment to anyone coming to Istanbul.
Aycan and Mert were easy to communicate with and arrival instructions were concise and accurate.
The Bomonti neighbourhood is far enough away from the touristic areas to give you a feeling of being “locals”. As for transport options, the Metro (Osmanbey) is 10 minutes walk away and a large Migros Supermarket is at the end of the street.
Being on the top floor, the wrap around balcony provides a nice outdoor space.
All in all, we would happily return here next time we are in Istanbul.
