The stay was okay, its equipped for everyday needs, and it has a perfect location.
That being said, this apartment is not "luxury" at all. Its just a normal apartment. I have no idea why it was advertised like that. It has only one air conditioner, the kitches is very small. It is very expensive compared to other apartments, probably because the location is very turstic.
The elevator was broken many, many times. So if you have problems going up the stairs, I would not recommend this place.
The staff on Airbnb was always helpful and quick to respond and the check in was very smooth, but paying 50 EUR on top of the already high price was not.
If I had to choose again I would go for a cheaper alternative, this was a little overpriced and not luxury as stated, maybe far from this place cause it's loud at night from all the tourists.
