The apartment was clean and in a good location. But the massive downfall was the noise and vibrations from the metro lines under the building every few minutes. We were unable to get a decent nights sleep during our 4 night stay. Marta and Paul down played this issue by saying we were the first to ever complain about this noise.... We really struggle to believe this! As it was very loud and starting at 5 in the morning until shortly after midnight, and happened every few minutes. We even tried to sleep using sound cancelation headphones unsuccessfully. All round the worst experience on Airbnb so far.
