Thank you 
@FuturoBA. I think you also bought a place not too far from mine.  How are your rentals going? I agree about spending the money to get it higher end.  I own a few rental apartments and I have been able to get more money with nicer furniture and a good mattress.  The biggest factor is that I get a lot of repeat guests that come back because it is nicer than most others.  I was surprised there isn't many things readily available at the high end. I either had to wait to get it shipped there or they had to make it.  My sofa bed took a while to make. So did the black out curtains which had to get custom made.
Thank you 
@CraigM! Yes I am excited when the next property in Palermo Hollywood finishes. I think it should be similar but I bought a 2 bedroom apartment in that building.  Mike told me you bought a 3 bedroom in that building so I'm jealous.  We will all have to celebrate once that building is done. I'm told that 5 of us bought in that new building.
That is the thing I hate about Airbnbs and mostly why I have rented hotels because a nice hotel always has decent mattresses. In BA, I rented a really high end Airbnb with 
@earlyretirement and it was great.  Very nice furniture except the mattresses were very cheap and hard as a rock. My back hurt for a while after that. 
I noticed the same thing.  Mike told me that most rental guests that are couples want a King bed but the price for a King vs. a Queen really jumps up so most people just get a Queen.  Or there might not be much room for beds in the small bedrooms in BA.   My bedroom wasn't huge but I took BuysellBA's advice to put in a King bed even though it took up a good portion of the room.  And so far that was great advice because people were looking for a King bed.   It seems like the key in BA is to do things that other owners aren't doing and you will have less competition that way. 
Thank you 
@Avocado! It did turn out great and I am happy. Originally I was going to buy with a building with a pool, gym and a bunch of amenities but I was told that those buildings have high HOA bills.  For my first purchase, I just wanted something low maintenance with low fees.
I was surprised it was so low but you can see my actual bill below for January.  The originally estimated it would be around $100 USD per month.  The bill was 71,172 pesos which was about $59 dollars.   I'm told it should go up as more and more owners move in.  A lot of the units in the building are short-term rentals.  
@earlyretirement bought a few for himself and about 6 for other investors.  They told me that water is included in the HOA bill but all the owners will get pro-rated amounts based on the size of their units.  So maybe it will go up a little but they told me it should stay under $100 dollars a month.

Sorry to hear your condo fees jumped up so much. But are you really trying to compare what bills were 20 years ago?? If I gave examples of everything I am paying in the USA that have jumped up from 20 years ago I would have an endless list.
I do feel for those in BA who are having to deal with this. I wouldn't want to pay those kind of monthly fees for an apartment.  But even still, my friend has an apartment like mine in downtown San Diego and he pays about $900 a month hoa fees so mine are about 8 X less expensive.   He does have a full time doorman around the clock and mine leaves at 6 PM.
