Isak was a good host. He left sweets, water, cereals and milk for us. It was nice and helpful.
The flat location is super. All we needed was in a few minutes walk range, including Istiklal street, Galata tower and Galata Bridge. But consider terrain relief! It was challenging to go uphill every day :)
The flat view is awesome. We looked at Bosphorus every morning. Flat itself was clean and very bright, we enjoyed it every minute.
But the neighborhood is SUPER noisy! Really really noisy. Cargo ships, seagulls and crows, cars and motorbikes, street tradesfolk, mosques, children - it's very hard to have rest when you hear them all. During Ramadan, it's probably even worth.
