I booked this hostel based on the reviews on Tripadvisor and it was exactly as expected. Small room, but clean. I really enjoyed the location - close to everything and you can walk everywhere (including the museums - Prado, Sofia Reina, the bars and restaurants around the Puerto del Sol, and the Gran Via shopping area). Hostel also has a free WiFi in the room - yes, it wasn't the best connection, but enough to check emails and plan the trip for a next day, and it's nice to have it for free (as thereare some other higher ranked hotels that charge for this service). A room was too small though, and wasn't enough air even when opening a small window. Overall though, would say that this is a very good choice for a budget traveller, just keep in mind that it's very very basic
