Pros: The view is absolutely gorgeous. The host is friendly and responsive.
Cons: We experienced frequent electricity blackouts, maybe half our stay, the hotels nearby had generators so they were fine, but we couldn't take a shower when we arrived until noon the next day. The elevator wasn't working because of that too. So we had to carry heavy luggage up and down the stairs, so if you have mobility restrictions be aware of this. The location is near Taksim which is convenient, but the neighborhood felt dodgy. I would rather stay someone slightly further away but safer.
