We stayed for 7 nights, it was great for us! The stairs are very steep if you’re on the second floor, so keep that in mind. The bathroom had a nice upgrade, very clean., quite narrow. The water heater is above the sink, so just be aware of how much hot water you’ll have.
The location is perfect if you’re planning on doing a lot of walking to the sites. We easily walked to the Blue mosque, Hagia Sophia, grand bazaar (keep in mind there are pretty steep hills and we are people who love to walk). The neighborhood is quite busy, calm mornings but you can find food and people are out well past 11pm. We stayed in room 4, which technically has a sea view! When we come back we would 100% stay here again.
