This is pure gold. Not only because the apartment is well located (near a ferry and near the Istiklal street) but also because Erhan is the king of hosts.
He was extremely attentive and helpful with every single detail about ins and outs of the place. Even before arriving to Istanbul he already gave us a detailed explanation of everything (transportation, communication, food, shopping, etc).
If you are working remotely you have to work in the dining room to avoid waking up the neighbours with zoom meetings.
If you are very sensitive to odours, be aware that bathrooms in Istanbul can have a really bad smell. This is a thing in Istanbul and Erhan has put TWO automatic fragrance sprayers in the bathroom working 24/7 and some instructions if the smells it's just too much.
Other than that I think you would love this apartment and you will want every host in Airbnb to be like Erhan.
