This is not a duplex apartment, these are 2 separate apartments in the same building (one above the other). There is no common area nor proper kitchen nor living/dining room in either apartment, it’s not a good option for a family coming together. In general the place isn’t in great condition, everything is quite old, the shower is moldy. Contrary to what is stated, there is no shower gel/shampoo nor oil in the kitchen, there is hardly enough of towels for 7 people. The beds are short.
The location is great, many nice streets with shops, restaurants, parks with playgrounds. There is also a nice seaside park at walking distance. The place is however quite far from the tram station.
