We stayed a full week at Tereza's historic apartment (her grandparents used to own a factory on which grounds the apartment is still located). The beds are comfortable, the kitchen spacious and great to cook in, and the little details and extras make the apartment a great home away from home.
Also, the TRAM connections are superb. They are 50m away and bring you within 5-10 minutes to the city centre. Further one has all groceries and little kiosks around the block. I would also suggest to check out the Vietnamese place just up the street.
As we were traveling with our 1,5 year-old we also found the playground within reach very cool :)
