I stayed here for a number of days, the night with this Wotif booking and number of days with G Adventures, including booking extra days after, it being their base hotel for Cairo nights of Highlights of Egypt 14 day tour. The hotel is interesting in decor. You've got I'm guessing pith helmet era English, Spanish, French aristocrats portraits on the wall who I'm guessing explored ancient Egypt sites, otherwise odd choice in Egypt. Lift is interesting old era one. Rooms I experienced a few varied, some were better designed, especially the bathroom. But aircon works, showers are decent, beds comfortable. No pool or anything really to do other than sit on chairs in lobby or on floors near lift so just stay in your room as the hotel is a sort of safe sanctuary in this neighborhood. Area outside you get constantly hassled walking around, "where you from?" "Come see my shop," What you want to buy" "spend all your money here" or followed around wherever you go by people expecting money for doing so even though you've told them you want to walk by yourself. One guy even kicked me because I wouldn't give him any (I'd told him constantly "I'm being blunt with you I'm not giving you any money" He's like is okay I just walking with you but then wants money at the end, acting like he was my guide. Likewise places around area you buy food, credit card machine suddenly isn't working, the bill has extra items in there.
Staff at Hotel Cosmopolitan though are great.
