Elsa is a warm, friendly, patient and helpful host. She answered in a quick and precise way. The appartment is great located - in the centre of a very popular Madrit' location, full of great tapas bars and discos. Is also very well located for joining all Madrid's tourist atraction which you can reach by foot or by a metro (the station is really closed). I highly recommend Elsa and her great place (very good for two person though).
