We were coming for 3 days only, the apartment was excellent and even better than we expected.
All needed facilities and etc: everything brand new, exceptional clean, kitchen fully equipped, ironing and coffee available.
Location: 5 min walking from metro, total 15 min to old town.
Steep stairs down- for us was perfectly fine (for older people, small kids, otherwise totally ok).
Mariola gave us really detailed and clear instructions and was answering quickly.
Overall we highly recommend it.
