I've just spent two most wonderful weeks in Madrid, and staying in Catalina's place made them even more enjoyable. The location of the apartment is really in the perfect spot - only a short walk to metro or city center, placed in a vivid neighborhood with a lot of nice restaurant and bars. The room itself is quiet, comfortable and cozy, the bathroom has everything you need. The whole apartment feels very artistic and charming. The hosts are great, Catalina and her family are such a nice people, trying to help all the time, and even one simple 'Hi' after a great day out makes you feel even better. You really feel welcome there. I was also able to use the wash machine when needed, I could even check out later the last day, I really had everything I could possibly need for a perfect stay.
The highest recommendations!
