An excellent place to stay for a single traveller to the city, walking distance to a lot of sights and attractions (though do not underestimate the hills of Istanbul, the roads are very steep).
The place itself is basic but very comfortable. The room can be a bit warm at times but the host has installed ceiling fans so it's fine.
only thing I was confused about was that I initially thought I had booked a loft, but I actually booked the ground floor that had a loft bed, but this didn't really matter to me.
all the facilities worked great. The host was also excellent at giving recommendations and responding to queries. A very nice touch was that he allowed me to store my luggage in another room on the check out day because I had a really late flight. this allowed me to have an extra day exploring Istanbul.
