We stayed at Deniz Houses, one of Kamils 3 hotels in Istanbul. Kamil is a great person and helped us by personally taking us to one of the other hotels and letting us choose the room. Coming to the hotel part, the standard room is compact but has everything one would need in a hotel room. The breakfast was also great. Also very close to Blue Mosque,Hagia Sofia, Topkapi, Hippodrome etc.The added bonus were the receptionists - Hakan and Ergun. Lovely people and they gave us all the information we needed..also told us the best places to buy cheap stuff and were very friendly. Sadly we stayed there only for a day since we wanted to stay in different places but if our other booking would not have been done we would definitely stayed at Deniz Houses. If given a chance will definitely stay there again..only to meet Hakan and Ergun.
