Let me say to start that overall the apartment (though not as nice as in the picture) was adequate. The security staff downstairs were very polite and the unit is in the middle of all things fun in Zona Rosa. Relatively clean but definitely in need of freshening up.
HOWEVER --- the bathroom was a mess. We are interior designers who also have a lot of construction experience too. So, take what I'm about to say for what it's worth. The biggest problem was that there was a fast and steady leak that continually flooded the wall and floor next to the john. Every time it dripped, it splashed anybody nearby (as in sitting you know where). The water had a very funky smell and we are convinced it came from a broken seal on the toilet in the unit above! ICK!!! I took photos of the leak. The paint on the ceiling where the water came from was 'bubbled' so we knew the problem has been going on for a long time. We brought the problem to the attention of the building staff, they just smiled and said they already knew about it, shrugged, and walked out.
Hm...
Next, the toilet didn't completely flush each time. Just a warning to save users future embarrassment.
Shower: No hot water for about 5 minutes after you turn it on. Sometimes no hot water came at all. But if you did get hot water, it did usually last long enough for two people to clean up.
I don't like to give anything but the kindest of reviews, but we found the dripping toilet water issue really offputting. Oh, it was bad enough that the floor next to the toilet was always puddled. Forgot to mention that.
