Several points:
1/ location is perfect, right next to Galata Tower. A bit overcrowded with tourists but it is ok. The view from the balcony and shared terrace is magnificent.
2/ the furniture and appliances could have been refreshed. We had to ask the doorman to help us with the washing machine. No iron and ironing board but it can be provided.
3/ towel need to be replaced. We found only 2, good we had our own towels in addition.
