We stayed a week at Cagatay’s appartement and it was superb.
The neighbourhood is perfect for a young family with children since it is calm, close to markets and ferry and metro stations (all at 5min by foot). Beautiful views of the Bosphore in 5 min walk. Delicious manti (Turkish raviolis) in the same building as the apartment.
The apartment in itself is very tasteful, spacious, warm and cozy.
The hosts (we had contact with Cagatay only) were very helpful and quick to respond.
P.S. we were very happy with Uskudar: there is a nice small bazaar , many pastry shops and nice cafes.
