First, the positive:
Great location, walkable to many restaurants and tourist spots, very comfortable bed
Now, the not-so-great:
So many mosquitoes. Some alive, some dead, smashed on the walls
Shower door is unstable and very narrow (if you're overweight, you won't fit into the shower)
The whole place really needs a deep clean. Cobwebs, dirt, dust, etc. everywhere. The floor had not been swept before our arrival, and we couldn't find a broom to do it ourselves.
Jose Carlos doesn't have much to do with the property. There are other people that you will communicate with if there's a problem (see more below), so it's easy for communication to break down or get delayed.
The sink did not drain properly when we arrived. Each day it got worse, to the point that water did not go down at all. We actually had to use the bathroom sink for washing veggies and doing food preparation since the kitchen sink was inoperable. It took a long time to get it fixed.
