This is such a great place to stay! The staff are incredibly hospitable and welcoming, and they go above and beyond to help their guests enjoy Istanbul. The Cube suites are located within walking distance of some of the main sites like the Hagia Sophia, the Blue Mosque, and the Palace. The apartment was clean, quiet, and comfortable, and I would definitely return. Don't forget to enjoy good conversation and delicious tea in the lobby. As a solo traveler this also felt like a very safe place to stay, and I would recommend it for first timers to Istanbul.
Thanks again for the wonderful time!
