I love this hostel, the staff makes you feel so welcome. It was my second stay and next time I will go back for sure. This hostel has also film screenings on Sunday nights (the night I happen to be there) which is very nice and relaxing, and might give you a change to meet some cool locals!
The Windsor just breathes history! I loved the atmosphere. I got a free upgrade to a beautiful room which was the same room Monthy Phyton's Michael Palin stayed in once, as I was told a few times. The room had lovely high ceilings and the furniture seems to be all original. Although old, it is a very clean hotel. Unfortunately i did not have a change to check out the roof terrace or the bar, although the bar is very famous. Just around the hotel there are loads of food stalls and cafe's also.
I loved my stay in this hostel, the staff is super friendly and I have met some wunderful people. If i go back to Cairo I am definately staying at Dina's hostel again.
