The appartment is very well situated and very calm, but it is important to know that there are a lot of steps to get to the building and to the appartment. If you are not in a good physical shape, consider a different option.
The rooms are a bit small but comfortable and clean.
The kitchen is so small that you can’t almost cook and there are very few dishes and cupware. It would be nive to have some more dishes and glasses as well as cutlery. And it would be also nice to have some cleaning items in the apartment.
Besides that, we enjoyed the apartment and Istanbul.
