We had an excellent stay in Istanbul. Location is just perfect, overlooking Galata Tower with number of trendy places in the same street. Easy to walk over the Galata Bridge or take a public transport in order to explore the city. Loft style studio flat worked very well for us.
As we stayed for a week a big plus was having a washing machine in the flat. We love walking so fifth floor apartment did not present us with any issues.
Communication with the host worked very well. Eyup was very responsive responding to the messages, and has booked a taxi for us to depart very early.
I would use the same apartment again.
