I like to be honest with my reviews, so here goes;
Pros:
The place is honestly one of the best spots I have ever seen and stayed at. The Galata view from the terrace is simply breath-taking, not to mention the view from the rooftop of the building.
The street on which the building is located is very calm even during daytime and there is a coffeshop/brunch place right next to the entrance.
The hosts are located at the hotel next-door so you can find them 24|7
Cons:
The shower and toilet are literally in the bedroom with only a matte glass separating them so you will have to arrange your toilet privacy.
The neighboring building is really close so make sure to keep your window-blinds shut.
Overall a great place to stay with amazing value! Would recommend it to anyone looking for a beautiful and safe location in the center of Istanbul.
