It wasn’t bad but it definitely wasn’t great. Overpriced for the area and overall building condition. Elevators out of order. Surroundings area has a lot of shrubbery resulting in an onslaught of mosquitos. No pool. No common areas to relax. No Security. There is absolutely nothing on the surrounding area other than a 7-11. Getting a taxi can be a daunting task. 20 minutes outside of the city. Not recommended for the price.
