Just returned from a 2 week stay at the Ambassador Suites, and absolutely loved it. Our check in was smooth, even though we checked in at around 11:00 PM, the lone employee escorted us to our room, and we were placed in a 4th (top) floor Master Suite, as we requested. The only concern was a few ants on the wall in our bathroom, which was taken care of the next day.
The Room: Absolutely spotless. Had a small refrigerator, with a micro wave. They supplied 3 or 4 bottles of drinking water each day, as there is a notice in the hotel not to drink the water from the tap, but that it is fine for washing fruit, brushing teeth, etc. Dishes, etc, are supplied, as well as a toaster, coffee maker, and a hair dryer as well. There was a comfortable sofa, and the bed was King Size, and yes it was somewhat firm, but that is the way we like it, so that wasn't a problem.
Complex: The grounds were fabulous, with well maintained pathways everywhere, which were good for jogging, or just an enjoyable walk. There were 7 pools, and yes, the majority were chilly, so they took a bit of getting used to. But there was never a problem getting a pool lounger, no matter what time of the day it was. The complex is undergoing various repairs, from painting the outside of some buildings, to doing some roofing or major renovations inside a few of the suites. They never started work excessively early, and were hardly noticed. The restaurant outside the main pool is great for happy hour drinks, (4-5), and the breakfasts were outstanding. (Omelets were to die for).
Staff, etc: As stated by others, the Ambassador, although separate from the Los Tules, is all part of the same complex. The office for the Ambassador is in building 15 I believe. They were very helpful. Both ourselves and another couple from Winnipeg, had a late flight, at 22:00, but as the rooms weren't being used that night, they allowed us to remain in our rooms till we had to leave for the Airport. That was a great bonus to us.
The Ambassador is a 45 min walk to downtown, and about the same to the Marina. If you don't like to walk, you can catch a bus just outside the complex, or a short cab ride.
Beach Area: The beach is quite nice, though pebbly in some places. Yes, the beach vendors will approach you as you walk along, but just a nod will send them on their way. If you think it is bad in this area, try the older part of Puerto Vallarta, where some of the hotels and restaurants along the ocean have to use the beach for tables and lounge chairs as their properties aren't large enough to hold everyone staying or eating there. Here, while you try and enjoy a few drinks, the vendors are in great numbers, and it is almost like you have to send one away every minute or two, which is rather annoying when you try and enjoy a drink and a few snacks. So the Ambassador area isn't that bad at all as far as the vendors are concerned. (Note: The Muffin man comes around most everyday along the beach, as he can be heard bellowing out "Muffin Man". They are great, and are only 15 pesos).
The Ambassador Suites was outstanding, and we will absolutely stay there again.
