First, if you're looking for the hotel, it's a bit in the back and on the left side when looking for it on the street. This is a basic, no-frills hotel located in Downtown Cairo, right within walking distance of Tahrir Square. The staff was very nice, but spoke very limited English, so keep this in mind. My room was clean and comfortable. The wifi was not consistent on my phone and faded at some points.
The rules about guests are very ambiguous -- I invited someone to my room very briefly to retrieve something and we were followed by a staff person who knocked on our door. Otherwise, no complications.
