I stayed with a friend at Laura's place and the apartment was perfect for our visit to Madrid.
We arrived fairly late at night but Laura stayed waiting for us in the apartment and even kindly offered to pick us up from the airport. We got the metro still as we had travelled with a few more friends who were staying elsewhere, but Laura provided us with great instructions on which subways to use so we got there easily.
During our stay the apartment was absolutely spotless and had everything we needed. The location was very convenient as you can walk to Tribunal station within 5-10 mins.
Would definitely stay again if I came back to Madrid!
