The location of the apartment was perfect - and having a balcony was wonderful. You do need earplugs at night - but it's a price well worth paying for the great day-time experience!
I do think the apartment overall could be more in keeping with the 5* location. The floors were dirty, cups tea-stained, holes in the bottom sheet for the sofa-bed and no fresh towels during a 4 night stay. This despite a 60 Euro cleaning fee required on arrival.
This does take the shine off the experience.
