We stayed here for a week in December. It is a lovely peaceful place. We had heard that Zanzibar was overrun with tourists - not Jambiani! It still feels very much like the kind of place where locals and tourists cohabit nicely. This may not be what everyone is looking for but for people that want an authentic experience Jambiani will ofer you this.
This place is very well done, rooms are spacious, clean and nicely furnished. It has an intimate atmosphere and is keenly priced. It offers a great location and has the benefit of a very nice pool area. Good food, again well priced. The staff, particularly in the restaurant were genuine and friendly.
The only negative point was that the rooms were a bit too hot (though December is a very hot time of year here) though when we asked we were given an additional fan straight away. If the ceiling fans were upgraded though this would probably make the extra fan unneccessary. Also the trips offered by the hotel seemed too expensive to us, so we went with the guys on the beach instead who provided a good service. Minor points though and I would gladly return here and loved my stay at Casa del Mar.
