The sofa is not at all suitable for two adult people. We had to put one person to sleep on the floor. The sofa is very uncomfortable.
The apartment was not very clean. We found hair in the fridge, dirty toilets, used tissues under the back bed and lots of dust. The Wifi connection was very poor in the kitchen and the back bedroom. It was impossible to adjust the heating and it went on all the time.
We do not recommend this accommodation for 6 people.
