We had a great time at Costa Del Sol B5. Very large, well appointed, very clean, plenty of room for big group. We've never stayed so far south in Cozumel before and I was very happy - far enough from town to feel "away from it all" but close enough to drive in for meals or excursions. The pool, beach and entry into the ocean was probably the nicest I've seen. We had little kids and they had no issues wading out into the swim area. My friend and I talked about how well decorated the condo was (loved the bedspreads and curtains!) and how clean the unit was. Also, having access to the washer/dryer was awesome, thank you!
