The hotel was easily accessible to the mosque. At the time of writing this, the main gate for Tawaf is gate 79, and the Sheraton is on the newly extended side, so we mainly used gate 114, there is more space to pray and less crowded and chaotic, which we preferred.
The staff were particularly friendly, and always greeted with a smile no matter what time of day it was. We arrived a bit earlier than expected, but were able to leave our luggage with concierge and then check in a bit later.
There is a bridge that will have access to the mosque in the future, but the building work for the mosque extension has not been completed, so this is not in operation yet. But bear in mind this the extension part and not direct access to the Kaaba.
The facilities, bed and room were clean and comfortable, and I would personally stay here again.
