Jaques' apartment is well lit, comfortable, and extremely well equipped. The kitchen has everything you could need, including spices. The location is away from the center but very close to the metro so you can be anywhere quite fast. A cornershop that opens basically always is just down the stairs. Finally, the apartment is very quiet. The bedroom is just over an inner courtyard and is ideal for sleeping late.
Jacques himself is a warm and dedicated host, and took time to follow up and make sure we were ok and answer all our questions about Madrid and the apartment.
