Posada Ruiz #2 was our second hostel in Antigua. It is quite basic with two outdoor sinks and no soap or towels available. The showerheads are wired with heaters but they were inoperable at the time of our visit, so we showered cold. We stayed three nights and were woken by loud music and crying babies several times. The mattresses were beat-up but of higher quality than those at Kafka or Jungle Party. Double rooms have electrical outlets but singles are plugless.

Despite its problems, Posada Ruiz provided good value at the very bottom of the lodging market. For 40Q/night for a single, I'd stay there again.

I love the Posada Ruiz 2. It is the best of the very cheap hotels in Antigua. Antigua has a very wide range of hotels in price and quality, ranging from $2 US to $500 US. per night. Posada Ruiz 2 is about 4 US dollars but it is the best of the hotels in the under $10 price range. They have 3 hot water showers that are cleaned in the morning and afternoon, and they change the sheets every day. I'd advice you to get a double room even if you are alone as it is only an extra dollar.
The workers are very diligent and very nice (especially Gloria and Maria, the two indigenous sisters). And the other guests are mostly well-informed european backpackers who are staying for a week or two on their way through central america.
