Julián is an excellent host. Communication was clear, he kindly gave us lots of recommendations and always replied promptly to messages. For check in, he met us with the keys and gave us practical information. The apartment is well situated - you can walk to the centre or to Chamberí and there are many buses / metro lines close by. The air conditioning worked very well and the flat was spotlessly clean too. Overall, an excellent stay and I would stay there again!
