We loved our stay here. Everything was very close & the room was extremely clean. It was more like a hotel than an apartment. We got fresh towels almost every day and the room was regularly cleaned.
What you have to keep in mind: Istanbul is a very large and busy city. So it´s quite loud. Because the apartment is in a popular and central area its sometimes a little bit loud too. But that's nothing to really worry about and we will definitely come here again!!
