You will not find a better-located apartment in Beyoglu or even Istanbul, for that matter. It is ideal for all sorts of travellers. The apartment is over two floors and is big, comfortable and spacious with terrific views and extremely quiet.
If you are arriving, particularly if it is a late arrival, then the reception is in the building next door, go there for your keys. Again for late arrivals, there is no welcome pack so that you can make a sandwich or a cup of tea/coffee or suchlike. Equally, there are no cleaning materials or cloths for general kitchen cleaning.
We had one interaction with the owner, which was less than welcoming. I understood that we were in the wrong by not wearing a mask in the building, but we all know that there are many ways to skin a cat and the aggressive tone was very offputting. So we decided there and then to have no further communication with the owner. Only to receive another message that evening in the same aggressive tone.
The wearing of masks, under Turkish regulations as well as in most other countries, is for medical facilities or areas where they are likely to be crowded, like public transport. I think we were in a building with seven apartments, and over the course of the nine days, we never encountered another person visually or aurally.
Do not be put off by our review. Our review of the apartment is second to none, you will not be disappointed as distinct from the owner who may have been under pressure, I don't know, but I tell it as I found it.
