Tolga's place is in a great location - it's right off of Istiklal Avenue and has a ton of restaurants and shops around. It's also right above Tolga's bar and club, which made it very easy to finish our nights out comfortably (don't worry - the sound insulation was so good we couldn't hear a thing from the apartment). The place was an excellent value and provided all of the items we needed.
Tolga himself, his wife, and his staff were incredibly sweet and accommodating. They helped carry our bags up/down, made us feel at home, and even surprised us with a birthday cake for my girlfriend's birthday.
Overall, we had an excellent time and highly recommend staying here!
