Four of us stayed in Vanilla 2 for an extended weekend and had a wonderful time in Krakow.
It is brilliantly located so that a walk to the Rynek (5mins), or Kazimierz Jewish District(15mins), is no more than a short distance away.
The apartment itself had three large bedrooms that could sleep a lot more than the four we had, 2 bathrooms, a kitchen/dining area and a decent sized balcony. The facilities were top notch. If there were to be a constructive criticism, it would be a lack of lounge area, but that was not important for us - just bear it in mind if you were to want to be at the apartment more.
The booking was flawless and flexible and could not fault it.
Would recommend to anybody.
