I did the Sheraton in Montevideo...just across the river from Buenos Aires.
TBF, not all hotels get in right abroad.
Bear in mind mind i'm not talking 4 star hotels below (i think almost any 4 star, here or abroad is going to be more than ok)
Also bear in mind these are not for the most part holiday or resort hotels.
Can't remember some of the names but one in Burriana in Spain, they couldnt have been more indifferent if they tried.
Golden Arches (IIRC) in Limassol...hmmm..bit of a dive.
Another hotel in Limassol, only stayed a couple of nights when the Icelandic volcano went up...the whole deal (hotel) left me cold.
One in Carmelo Uruguay, a right dive, but TBF, the staff were a mix of mickey taking, but quite attentive. Never quite knew how to take them. Took 8 days to get some laundry done

Its not as though the hotel was busy.
I dont think ive been in a bad 4 star...
