First of all, if you get the top floor apartment — this seriously has one of the most beautiful views in Istanbul for the price. It’s walking distance (10 mins or less) to Grand Bazaar, Blue Mosque and Hagia Sophia. You could even walk a little longer to Spice Bazaar. It’s in such a perfect spot.
The apartment was clean and comfortable. It could sleep two people on the bed and maybe a third on the couch. Hot water lasts very long, too (which was perfect for cold winter and tired feet). FYI, the mosque across the street will wake you up with morning call to prayer at 6am but that is usually my wake up time so I didn’t mind. Be aware you will need to climb steep stairs so be prepared in case you have heavy luggage. Otherwise, the hosts were so kind, helpful and understanding when we had flight delays due to snowstorm. Book them!
