We did not get to meet Alina but her mum welcomed us at the apartment when we arrived. They were very accommodating and understanding. Her mum waited for us when our flight into Prague got delayed so we arrived later at night than expected. They also allowed us to leave our luggage in the apartment for a few extra hours after checkout because our flight was later in the evening.
The apartment itself was well-equipped and in a fantastic location - Everything is within walking distance. It's close enough to all the things you want to see or do in Prague, yet also in a quiet area which means that there is no disturbance at night when you want to rest. Would definitely stay again if I come back to Prague!
