Nico's apartment is very conveniently located with easy access to downtown Madrid via metro or bus. The apartment is very comfortable; it has three air conditioning units, washer and dryer and a very well equipped kitchen. And Nico left the refrigerator stocked with juices, eggs, bread, sauces, pasta and lots of other things.
Nico is an outstanding host, ready to help in any possible way. We had a minor problem with one bathroom and he was there within five minutes to fix it. Next time we go back to Madrid we will try to stay at his place.
