We stayed at Meltem's place for 3 days and it was wonderful! The apartment is beautiful with two full bathrooms, two bedrooms, and an excellent view of the church that is literally across the street. The apartment is well stocked with everything you'd need. There is a mini-market on the same block where you can buy water and other necessities. The apartment is on a fairly steep hill (but then again so is everything in this part of Istanbul), but after a short 5 minute walk up the hill you are on Istiklal Street with all of its shops, restaurants, and coffee shops. The Galati tower is very close as well, and there are a lot of cool coffee shops and bars next to the apartment. The Sishane metro is only a 5min walk away as well. Meltem was wonderful and met us at the apartment when we arrived. Her company's office is in the same building as the flat, so she was always available and very friendly. I highly recommend staying here during your next trip to Istanbul.
