I write this review from the hotel itself, this being my third stay.

Pros:
- Free, direct, comfortable shuttle from the airport
- Heavenly bed
- Good AC/heating with modern controls, no noise, and pretty comfortable rooms with large modern TVs
- Impressive pool and gym
- Location

Cons:
- Loves to nickel-and-dime. Forgot your toothbrush? They'll send one up, but remember to sign the receipt (and its carbon copy) and pay maybe $7 for a very cheap Chinese toothbrush. Same with the Internet. One free bottle of "Salvavidas" water (not even spring water) with the rest charged at $2.75.
- One of my rooms didn't have blackout curtains; this one only has one so half the window is not covered
- Requested the concierge two simple tasks separately; for the first, she promised to call back but never did. For the second, I had to call back and no one had heard of the request
- Requested a reservation change, was assured it was done and it hadn't been
- Had a meal at the bar (bad), a few breakfasts (average) and a plate of room service yoghurt, fruit and mint. 15 mins after ordering the latter, I get a phonecall giving me a choice of yoghurts. 20 mins after that I get a fruit plate with no yoghurt or mint. (?)

Two of my colleagues checked in (on different days) as SPG platinums; one got a v nice upgrade, whereas the other one didn't. The 50% upgrade chance (on a very low sample!) is good.

It gets 4 stars because of the price, but this hotel needs some service improvements to be on par with the top-class business hotels it deserves to be grouped with.

This hotel has a great look. Elegant, international, business looking and close to what they call ZONA VIVA where you can have some fun in bars and get some dancing thu-sat (those are the best days). The pool is great and if you like swimming you can actually "have a good swim" and get into the hot tub afterwards (located next to the swimming pool...outdoors too).
They pick you at the airport and they offer free shuttle service once you leave the hotel. Room service is delicious...service is excellent and fast. Beds are incredibly comfortable!

Great location near many restaurants and a short walk from several museums. Also ate one night in the hotel restaurant and the food was very good; nice that they give free water.

this is one of the oldest hotels in guatemala city, part of the westin chain and classic decor. The restaurants are OK.
