Mixed review: First of all Ahmet is a fantastic host and the location was perfect for our family of four. Ahmet made us feel very comfortable and helped us with any questions we had, we would love to stay in the apartment again.
The downside is that the bathroom and one of the bedrooms have mold issues. We opened the windows, closed off those rooms, and used them as little as possible. Once the mold is properly cleaned we happily recommend this property.
Other notes: Beds were comfortable, linens were clean and fresh, we loved having a dishwasher and laundry machine, WiFi was usable but sometimes slow or unreliable, neighbors were occasionally noisy (some nights we needed earplugs), location was fabulous and we appreciated the quick walk uphill to the tram and bazaar and Sultanahmet neighborhood sites.
The apartment suited our purposes and we hope the mold issues are addressed, we'd love to come back and see more of Istanbul. We're also wishing Ahmet well, he's such a kind host.
