Really nice place, it really did feel like home. Hosts spoke English and they were really nice and helpful, they helped us for PCR testing. Really clean toilets and showers. The thing we enjoyed also was the common space, it was comfy with infinite supply of coffee and tea, with a lot of social games as well. Kitchen had everything.
The location of the accommodation was also really strategic, very close to tramway (which would take you to most places), located in the middle of the old city, nice for night strolling and exploration. Quite a few markets and restaurant just 1 minute walk away.
In conclusion, I would happily come there again for our next trip to Istanbul.
