Overall, our stay was pretty good - most of the staff are friendly and the room was clean and everything you'd expect from a hotel room.
Arriving at the hotel, it doesn't have the clearest sign - it looks like the hotel is called Hotel Antofagasta although on closer inspection there is a squiggly P afterwards. Maybe this justifies the reaction of the doorman when asking if we were in the right place (in Spanish) as maybe he thought it was a silly question, but I think just pointing at the doormat (which does have the name as you'd expect to see it) whilst frowning as his response is a bit rude.
The free welcome drink at their bar is a nice touch and the room was clean. I slept quite well - the beds were quite comfy, although if you do book a 'City View' room, bear in mind that the windows don't block out the sound at all, and it's right next to the main road through the city, which also includes a small train track.
