Excellent location in a quiet area facing the sea. A small Carrefour and a Starbucks are nearby. Taksim Square is not far and can be accessed on foot or by taking the F1 from Kabataş. A T1 tram stop is right in front of the building and the tram can drop you directly at Sultanahmet.
Nice apartment with a spacious bedroom. The kitchen is well equipment and the washing machine in the bathroom is a plus.
Erdem is a very nice and helpful host. We ended up renting his second smaller apartment in the same building as well. Highly recommended.
