Really nice place to live on a very quiet suburban-atmosphere-area of the city, with cosy 2-floor buildings, but you need only 5 minutes to get Retiro park (most beautiful park in the world, i think) from there, and maximum 10 minutes to get great art museums. To get centre of the city — 20 minutes of quiet walk.
Jose & Maria are very hospitable and open people, and appartment is very comfortable and have everything you need. 5***** and highly reccomends.
