The apartment failed to accomplish the basic requirement: ability to sleep. There is a family of neighbors downstairs that are unbelievable noisy. Their children are screaming on the common staircase, their mother shouts after them as well, it feels like the entire building is owned by them.
On the other hand Stella was very kind and called them once or twice.
The rest, the location, the apartment interior was great and as expected and if this problem was solved it would be a 5 star stay.
