The Felipe II looks impressive on Hotels.com and is the most expensive hotel I stayed at during a tour of Argentina but it was very disappointing.
On the positive side, my single room was a good size.
However, the room was a bit shabby with mildew in the shower. There seemed to be a light missing in the bathroom too. My room was at the back of the building, looking onto the backs of other buildings. There were lots of pigeons there, and several balconies and landings were thick with pigeon droppings. All night, these birds were making a noise which disturbed my sleep. Also, every half an hour or so, a really loud air conditioning unit started up which didn't help.
The breakfast was also poor. If you look closely at the photographs on the website you will see ham and cheese. Well, there wasn't any of that. You will also see a lovely display of fruit. That's there - but it's plastic.
Not a good experience.
