These apartments are really nice! They are really clean with a great pool area and restaurant, the staff are really friendly too! I know someone that stayed there for 6 weeks and we spent some time up there. They are situated off the top of the west end so they are really handy for cafe mambo ect without being in the hustle and bustle of the west end.
We stayed there one year and had a wicked time. As you said, it's not the hilton but the staff were were dead on and the atmosphere in the whole hotel was wicked. Bad points are it can be a bit tricky to find and it's in San An.
