Thekla is great host. She was really flexible with early morning check in and afternoon check out, and she was available for all questions that we have before arrival.
The location of apartment is perfect, it's in the center but street is quiet so can get really good rest. You need only few minutes by foot to Aristotle square and Hagia Sofia and maybe 10 minutes of slow walk to the waterfront and White tower. No need for use of public transport. In the area you have everything you need, grocery shop, pharmacy, bakery, green market, restaurants... Apartment was nice, clean and had all necessary accessories, even more than that and I would definitely come back again.
