We had a really comfortable and enjoyable stay at the apartment. It was easy to get to (It's easier for the.Taxi drivers if you say that it's close to Galata Door Hotel). There is a metro station close by as well and we mostly walked to Istaklal St (5 mins) and Taksim, Sultanahmed (20 mins), harbour for boats to the Asian side (5-7 mins). Erdem was very helpful, gave us some useful travel tips and was very accomodating with check in and check out. The apartment was perfect for the three of us. The location is perfect since it's around the corner from Galata but the apartment is on a side street so it's relatively quite. There wasn't any noise from the street at night time. The bedrooms are spacious and the heating worked well since the weather was a bit chilly when we visited in Feb. The bathrooms are a bit cramped but the shower had good water pressure. We didn't really use the kitchen or washing machine etc so can't comment but looked like the apartment had all the main amenities.
