Great little apartment. Great location with easy access to the metro. (Buy the 2-5 day passes at the airport for travel on all public transport).
The neighbours were a little noisy in the evening, but have good taste in music so it was ok. (It was a public holiday too so that's probably the reason)
Great chocolate shop and tapas 2 minutes walk away on the way to the amazing cathedral that's only 5 minutes away.
Highly recommend.
