We stayed here overnight in route from Honduras to the airport in San Salvador. It's on the 2nd floor of the King Quality Bus Station (KQ is a fantastic way to travel luxuriously city centre to city centre in Central America for relatively cheaply by the way) The hotel itself is on the 2nd floor (the DO have a freight elevator which is very handy) and check in was very swift. However the spartan rooms were just borderline clean; the linens in my room were very sparse and my only towel was ripped down the middle, but the maid had folded and used it anyway. The air conditioning in my room worked well, but the unit in the larger triple room was old and beat up and didn't work well at all, especially for three people. They must have problem clientele, because there was a notice posted on the mirror of the charges for breaking the various bits of furniture. The lighting was dim at best and there were no three pronged outlets and no adapters available at the front desk. They do give you breakfast though, and you're supposedly entitled to an hour's internet use on the public computer in the lobby, but it was down when we tried it.
This was an alright place to crash late night after a long day traveling, and they can get you to the airport in 45 minutes, but I certainly wouldn't recommend this for anything other than a one night dive.
