We loved staying here! My partner & friend and I worked remote from this place for 3 weeks and had strong wifi & great spaces to work. There are two desks to work at which is really nice. The location was great for us, it's a little farther out of the main tourist areas but very easy to access the main points of interest by metro & bus. It's 4 stops to the T1 connection to Sultanahmet & only 2 stops on the metro to Taksim/Galata. Grocery stores, bars, & restaurants are all within a few steps away.
The host was so helpful, communicative & kind. Two things to note are that there's no air conditioning, but the breeze is usually strong enough and with the windows open there was good air flow but it did get rather warm during the day. The other thing is that the stairs up to the apartment are steep & windy and there is not an elevator. This did not cause us any issues - just something to be aware of. Overall a great value and would stay again! Thanks for a lovely introduction to Istanbul!
