Perfect apartment in the most amazing and convenient location. Walking distance to everything. The Royal Palace is literally a few streets always (not even 5min walk).
From the balcony you can see the Opera Square yet at night in the apartment you can't hear any noise. Madrid is such a lively city at night so it was great still being able to get a good nights sleep.
Apartment is big, lots of storage and recently renovated.
Hosts are amazing! Gave great restaurants as sightseeing suggestions that did not disappoint.
