The "hotel" is actually called the "Residencia Flacso". It is a hostel-like arrangement serving as student housing for the Flacso graduate school. I guess they make extra money renting out the rooms Flacso doesn't use. Don't expect a view though, there isn't one. I paid $38 per night for a single-bed room with bathroom (toilet, sink and shower; no tub). The room was clean except for the filthy floor. White socks were black on the bottoms after just a few minutes. The bed was hard, the pillows flat. Otherwise it was an acceptable $38 room. As others have mentioned, taxi drivers have a hard time finding it. I found that telling them "San Salvador y La Pradera, cerca de La Carolina" helped narrow it down for them, especially from the airport (which by the way is 50km away and a $25 taxi ride). The lady running the hotel is a fantastic person. She'll bend over backwards for you and is super friendly. The rest of the staff (members of her family I think) are not quite as friendly, but they are courteous and helpful. The hotel is in a nice 'sector' (neighborhood), and I felt perfectly safe walking around even after dark.
