Not for 4 people. As all the other reviews mention I can confirm this is a brand new apartment and building structure, really well furnished and equipped. Location is also excellent. However, the sofa bed is awful and should not be considered to accommodate even 1 person. The structure is very weak even for me weighting 60kg. I could not sleep at all!
Another minor issue we had is that the kitchen had good appliances but no soap was provided to clean what you use if you need to do that for some reason, they probably expect you to buy it yourself.
