Great stay near all the local attractions in Istanbul's old town (Sultanahmet). About 10-15 minutes walking from the Havaist airport bus, though there are hills and cobblestone roads, but definitely manageable.
This place is actually part of a budget hotel called Kadriga Antik, if you want to look up additional information online. Rooms are a bit dated, but has everything you need for a quick trip in Istanbul.
Host and the stuff was very friendly and quick to help with any questions or concerns. I recommend downloading the BiTaksi app when visiting turkey as Uber does not work as of June 2019. About a 8 minute walk up a hill to the local Metro station as well. Small convenience stores and restaurants are nearby, including a local Turkish Hammam just around the block.
We'll definitely look to stay here again on our next trip to Istanbul.
