Really lovely, clean flat. Very good location. Had some issues with checking in and out. Owners had arranged a taxi to pick us up but it wasn't there so we had to make our own arrangements. Cleaner was then meant to be in the flat when we got there so we could drop our bags off, she wasn't so we had to wait 2 hours. Then on check out we got locked in the building. Took 8 calls to finally get through to someone. Took over an hour to get out which was a complete waste of our fast few hours in Madrid.
