Great location, albeit a distance to walk from the train station.
The room is very clean, and I'm sure you would appreciate the balcony view.
Breakfast is fantastic. And we loved that there was a hot/cold water dispenser and hot Turkish tea that we could grab anytime we needed to warm ourselves up.
I would definitely recommend this place to my friends. Alihan is also very responsive and helpful in answering queries about the place.
If there was an opportunity to return to Istanbul, I'd come back to Deniz Houses in Çayıroğlu.
