This is a older hotel recently rennovated with hardwood floors, fresh marble bathrooms, and very firm mattresses. The rooms are rather small by U.S. standards, but are more than adequate. We had a "suite", which was basically two connecting rooms with one bathroom. The water pressure here in the shower is amazing! Nothing beats a hot shower after "haggling" with the vendors in the Plaka. You can get a room price that includes breakfast, but in my opinion, it is not worth the 5€. Just pop next door for great coffee and a spinach or ham and cheese pie. The staff are very friendly, helpful, and speak very good English.
The location of the Cecil was prime for us, situated between two major metro stops (Monastiraki and Omonia Square), a short walk to shopping in Monastiraki and the Plaka one way. Going the other way, you have the flea market, and fruit and vegetable markets.
The Cecil has a wonderful rooftop view of the Parthenon! At the time we were there, there were no tables or chairs on the roof, so we brought our own and enjoyed afternoon wine, sunshine, and a great view!
I must mention the great old Otis elevator -- it will hold two people max, but it is truly a beautiful piece of work. The spiral staircase goes up around the elevator (see photo). We paid 108€ per night for two adults and two children. There is air-conditioning. I recommend asking for a room on the "quiet" side of the hotel -- there will be no view, but very little street noise. A single room for two runs for about 55€.
