Great apartment
Good location - few minutes walk to Demirören İstiklal AVM shopping street with bars, clubs, restaurant, street entertainment etc
Easy to get a taxi or walk. 11 minutes taxi ride to Galata Tower and only about 35 Lira = $3 (ask taxi to meter the fare everywhere you go)! It's the cheapest way!
To cross the bridge and see the blue mosque and palace etc it was 70 Lira = $7 but a bit more to come back. Once there you can walk to most of the sites.
The apartment was comfortable, has dishwasher, washing machine, fridge, stove and oven. Small grocery stores near by for convenience. Heat and air conditioning. Dishes, pots, pans, utensils were all you needed.
There is a pool and sauna for the building but unfortunately it's closed on Monday's (which I didn't know) and when I tried to use them they were not open so I can't comment. I believe the pool and sauna is open 8am-930pm but the front desk can confirm. Safe location, 24 hour building security and front desk staff available.
I would highly recommend this accommodation and I would stay here again :)
