Host: Anastasia was prompt to respond to queries, and very helpful.
Location: The flat is less than 30 seconds from Cheuca metro station and a little square with really tasty restaurants/bars. 5 minute walk to Feuncarral (a handy shopping street) 15 minutes to Gran Via.
Flat: Clean, compact, as described. Little balcony to watch the comings and goings of buzzy Cheuca. Noise not an issue despite being in the heart of the action.
Would recommend wholeheartedly.
