There is nothing 'boutique' about this hotel. It is pretty much a dump. It's close to the north end of Ave 5 if that's your thing. It is also a short walk to Encanto Beach, and included access to the decent Martina Beach Club (though you need to get there EARLY to score beach lounges on busy days!).
Cramped, musty, filthy rooms, narrow stairwell and no elevator, air conditioning that doesn't blow cool, every wall fixture in the bathroom torn off and painted over, water dripping from the ceiling (literally... I was awakened several times in a very poor night of sleep when water drops splatted on my face). There is no bedside lamp, but that's OK, the sheer curtains let in a bright glow from the courtyard area all night so you can practically read in bed.
Special shameful mention to the Expedia listing, which was either mistaken or an outright lie in just about every respect. The address shown in the listing map view was several miles away, and a much less desirable neighborhood west of the main highway. That's the sort-of good news. The bad news is that the address included with the email confirmation was also wrong and led us to walk about a mile out of our way to a residential neighborhood. The further bad news is everything about the listing was misleading. It said it was 415 ft² room, it was more like 150 ft²... It said two king beds. Nope, two doubles, with a total of exactly two pillows.
Terrible hotel, and lousy Expedia listing.
