Read other postings re reserving at the hotel, and, upon arrival, of being sent to the sister hotel across the street. This is my experience, as well. As my visit was in the winter, the main hotel does not appear to be open - just the restaurant and the Dar Baibou.

The room was basic,and clean, and had a heat/air cond unit, with a remote control. I was there for one night in early December, 2010, and although the heating unit worked, I was still cold.

The staff was very nice, and attentive.

Lunch or dinner is included in the price, and it is served in the actual Casa Hassan building. The restaurant is rustic and charming, with a wood-burning fireplace. The menu has a number of traditional Moroccan dishes. The harirra soup was the ultimate comfort food on a cold, rainy night, and the meat tagine was tasty, as well.

Breakfast was basic Continental, but the quality and quantity were good.

This restored villa is in a great location in the medina. Ask for a room in the new building as here the rooms have more natural light, are larger and quieter than in the older part. Make sure you have a hammam with massage - an unforgettable experience! The restaurant is across the lane.

We stayed at the Casa Hassan for 2 nights in late May. As another reviewer commented the price changed from the time we booked it a couple of days earlier to what we were told the room rate was when we arrived.
The woman at front of house was friendly and helpful.
The room was a generous size and had the potential to be nice with the furishings and decoration, but it felt very unloved. The room was semi-clean but more thprough cleaning would have improved it.
The room rate included breakfast and dinner. Breakfast was not up to the usual standard of other riads or hotels we've stayed in Morocco. As with the room, it felt that it was provided without much care or love. Dinner at the restaurant over the street was very good.- staff were very friendly and the meal was like a good home cooked Moroccan meal.

I have booked Casa Hassan on several occasions and was about to do so again for this summer when I read the reviews on Trip Advisor. They made me think twice about booking there again because, although I´ve booked and paid three times, I have never actually stayed there. Each and every time upon arrival we are taken to the sister hotel, Dar Baibou. Its not that I don´t like Dar Baibou but for example last year I booked in January for June and was specifically promised Casa Hassan, yet I´ve still never seen the bedrooms there. We have always put up with the rooms they have proffered and, especially if it’s the roof terrace rooms at Dar Baibou, they´re great and you have the terrace and covered chill-out terrace lounge to yourselves. The central location is good, especially if you´re only staying for one night, but its not unique. For longer periods, we usually stay in a rural hotel.

I´ve now booked elsewhere in Chefchaouen´s medina for a one night stopover in July this year.
