Midas looks nice and is well located in San Ignacio. Even though it's ont the edge of town, you can walk to most places. For exemple, we walked to San Ignacio Resort for the Green Iguana Conservation Project tour (20 minutes), then walked to Cahal Pech ruins (another 20 minutes) with 2 kids.
On site, the maid staff works well. Our rooms were done everyday. The pool area is quite nice. The bar was always staffed when we were here. Keep in mind that locals can have access to the pool without sleeping at the hotel.
The only problem we faced was that it wasn't quiet at all. We've experience some noice late at night (midnight) and early in the morning (6:00). Still, this wasn't the worst as this could be considered normal. There was one instance, during saturday night where there was a group of young people talking and laughing hard in the pool area from 3:00 to 6:00 AM. When I went to asked for less shouting, I was told : ''relax, it's the weekend.'' I can't say if I had badluck or if it's often like this. All I know is that there isn't security or staff that can keep things quite at night.
