Katherin is a great host, so friendly and hospitable and at the same time very discreet. The room is clean and quiet, the bed comfortable... Katherin's place is easily reached by public transport, it's also a 15 min walk from the Atocha station where you have a very convenient express bus connection to the airport.
I had a very nice chat with Katherin :-)
Un buen encuentro! Gracias!
