Our first trip to La Paz. Both my wife and I did not respond well to the altitude. Literally everyone on the staff was friendly, helpful, and bent over backwards to make it a good stay.
Special thanks to the concierge who was incessantly helpful, and to the people in the restaurant and room service, as our lack of mobility caused us to eat most of our meals at the hotel... which was a distinct pleasure.
I recommend Hotel Europa La Paz without reservation.
