Yusuf’s place aka Cube Suites is a small apartment building with around 12 flats over a number of floors. We were given a different flat to the one pictured, but it was not drastically different. The place can be difficult to find as it lacks signage, so GPS is recommended. A small supermarket is right next door and the area is very well serviced by shops and food outlets. It is a short walk to all the major historical sites, including the Hagia Sophia, the Blue Mosque and the Grand Bazaar. Do note it is a very steep walk. I stayed with my partner but I would have felt unsafe in the local streets alone, but I suspect this is typical for this part of Istanbul (so don't let this put you off staying here, just be cautious) Yusuf works with a team of staff who are all knowledge and professional. Yusuf handled our check in, which was incredibly informative and included a free coffee. The team assisted in booking transfers, organising laundry, booking a day tour and the public hamam, this was invaluable as we had a short stay and cannot speak Turkish. There is no doubt our stay was thoroughly enhanced by their knowledge, assistance and friendship. It is akin to Staying at hotel but with more personalised service -- you never waited long to get quick assistance and advice. The private hamam (first use free) was a nice addition to the experience. Overall it's above and beyond an Airbnb, highly recommended.
