The apartment is amazing. Clean, nice, beautiful view, it's ideal for staying while traveling. It looks like it's far from the center of the city, but it's next to a few tram lines and metro, so it takes no more than half of an hour to get to the city center. It has a big enough kitchen to cook, all basic equipment, and enough storage. One of the best but not obvious things in the apartment is a good washing machine with a drying system — that allows avoiding long drying and ironing of clothes, which is ideal when you do take not much stuff with you.
