We had a great stay! Perfect location, metro station Nuevos Minsterios is really close and you have a direct line for airport (line 8) and also for city center (line 10). The fact that was self-check-in was perfect for us because we arrived late at night. The flat was very clean and it had all needed for a holiday. The balcony is a plus and really nice to relax and have a glass of wine! I recommend this flat and I would definitely return if I have the chance.
Many thanks!
