This is a nice apartment in a nice neighborhood. The hosts are helpful and easy to deal with. There is excellent grocery shopping nearby. Also nearby are a pleasant park, and a tube stop accessing two lines (the number 8 and the number 4).

If you are a tourist the main drawback is that the flat is not close to central Madrid where the main tourist attractions are located. You'll need to travel in on the tube, and probably then by bus as well. This is convenient and easy, but it takes time. For example, to get to El Prado takes about 50 minutes. If you're only in Madrid for a few days you'll probably want something more central. On the other hand, if you're staying longer (I was in Madrid for a month) this is a good cost effective solution.

The kitchen is rather cramped. I did manage cook many meals in it, but it's a bit of a struggle. Otherwise, the flat is roomy, with plenty of storage, nice furniture, air conditioning, dish washer, and clothes washer.
