The location and apartment are great. The bed is comfortable and the shower is nice. We had everything we needed, except a wine key. I'd suggest buying a twist off cap bottle.
The only real cause for 4 stars and not 5 has to do with additional fees. It is exactly as written in the description, but paying 20 euro to leave your bags a couple hours just felt unfair, especially when this is a standard service and any hotel and every Airbnb I've stayed in. Anyway, we payed it because of course we didn't want to carry our bags on our last day, but you could probably find cheaper at the train station.
