We recently completed a 10 day visit. We stayed in the 21st Floor Hotel. The hotel met all of our needs, it is centrally located just off King George and Ben Yehuda and is walkable (for most) to the Old City & Western Wall.
The suite itself was very good, a small, but full kitchen, ample space in an open living room/dining area, 1 1/2 bathrooms, an excellent shower, and nice sized bedrooms.
Last but not least was the staff, everyone was very nice and very helpful, we were especially impressed with Oz, and Anas was extremely helpful as well.
