The location in Sultanahmet Istanbul is fantastic. You can walk to many local sights like the Blue Mosque and Ayasofya, as well as walking along the waterfront. Public transport is very close. The neighbourhood is charming and cozy, with friendly businesses nearby.
When the first room we were taken to had a strong chemical smell (?) Ercan was very accommodating to move us across the road right away. We stayed in a larger suite for the rest of our time there, 10 days, for the same price we would have paid for the smaller one. That was a bonus because it was a more suitable size for two people, with two rooms and a decent sized bathroom. The view over the Marmara Sea was wonderful!
It is best to rent this suite without intending to use the kitchen for cooking. We gave up on that idea after the first day because the hot plate did not get hot. When we asked for a working one we were told it would be looked into but did not hear back. We did not hear back about another set of keys though we were told it would be provided. This kitchen is fine to make cold salads and fruits, perhaps sandwiches.
We had a change of towels every couple of days and changed sheets one time in the 10 days. The cleaner offered to come in every few days.
This is a convenient location to explore Istanbul from, with a great view. Ercan is a friendly host. I would recommend a short stay here (no cooking).
