We had a great stay at Celma and Gert's place in Madrid. We had an overnight flight and arrived before check-in. Since the previous tenants had left early, we were able to get in to the flat, drop our bags and freshen up before heading out. It was very nice to have that extra time., and we really appreciated the kind offer. The location was perfect and we walked everywhere. Very easy to take the subway to and from the airport as well. Tons of good food and bars within a 10-15 min walk. The flat is clean and has all you need to enjoy your stay especially a washer if you are on an extended stay. The street is busy so close the blinds and curtains when you sleep to block out the noise. Overall, we'd highly recommend!
