10 minutes walking from central hub - Puerta del Sol. Slightly less touristy bars & cafes nearer by in the Lavapies district.
Felt very professional, and very easy to arrive and leave the flat. The key system with the personal coded boxes is useful, as you only receive one key to the flat.
Carlos also very kindly allowed us to leave luggage in the room on our last day until 3pm.
Soap and towels all provided and kitchen nicely equipped with all essentials. No kettle (we're British!) but can of course boil water in a pan on the hob and there is a coffee maker
