Recommending a room is a lot dependent on the type of accommodations the monger will be willing to stay at. Does he mind staying in a 'one star' hotel to be close to the action?
Cascades is best in my opinion if you want to be very close to the action especially if you get a window room....then you can look outside and see all the SGs lining the alley...it's better than a picture in a room. You are allowed to take at least one chica for free to you room, maybe more and the chicas from HK, LC, and Miami all use this hotel. However, the rooms are maybe 1 1/2 stars at best, but it's decent has a bed, TV, and the showers are hot. ( we got other SGs hotels going for about $12 a night, but don't even rate on the star system, or they go the other way into the minus)
If you require a more upscale place then Hacienda de Santiago is the best choice, right across from La Tropa, however mongers who care about dangerous streets might be a little concern here, as there are lots of gang bangers, general lowlifes, and TJ cops around this hotel especially across the street. I consider this street a lot more dangerous that Articulo 123, but than I think the danger level on ART 123 is a joke. I don't think it's really dangerous , but like a said lots of lowlifes walking that part of town.
Leyva, is in a little better area right near Chicago, and a very short walk to AB and other bars, and the rooms are decent, better than Cascades.
If I'm staying with family I like to stay at the Villa De Zaragoza it's close to Revolution, clubs, and better restaurants, but it's a long walk to the zona, or a short cab fare.
