The Sudamer has some good things going for it. The owner, Carlos Eduardo is a stand-up guy who is very responsive to renter needs. He tolerates our hobby but in all seriousness, doesn't really approve of it.
As Western noted, the Sudamer is a long stroll to the Gulch. It's seven blocks due south from the Hotel Presidente; eight blocks south and one block west of the Hotel Del Rey.
One advantage is its proximity to Pantera Rosa, although as noted, not a good idea to stroll the neighborhood alone at night.
If you're a fairly experienced monger and this is your first trip to C.R., the del Rey could be heaven on earth for you. OTOH if you need a more tranquil hotel, check out the Hotel la Amistad. If you want girls on premises there are the Sportsmen's, Hotel Little Havana and the del Rey (and maybe the Morazan?) to choose from.
It all depends on your budget, level of mongering experience and how far away your trip dates are. Booking into the del Rey or SL may require some advance notice, as rooms can be hard to get in both hotels.
Welcome Edgar!
