The apartment itself is nice and clean.
However, it could go from a 3* apartment to a 5* with some improvements.
Wifi is slow - 20€ a month more and you'd get a fiber line.
The table is way too small for anyone trying to get work done. A 100€ Ikea table would solve this.
Old style filter coffee machine - Why not add a capsule machine for 30€?
The list goes on. The place itself is brand new, but clearly has been cheapened out. I'll never understand the point of spending hundreds of thousands on an apartment, to then save a few 100€ and make things less comfortable for your guests.
