To be honest we were a bit disappointed with the apartment. I have to say the hosts were very kind and responsive. The place was good located and was clean. The problems were:
The apartment is pretty old so you could hear everything happening with the neighbors and outside (Kids screaming at night, the windows were not sealed so with the wind and rain the water came inside and every night a constant whistle noise)
To have a shower meant waiting 5-10 mins to get a bit of hot water ( waste of water and time) and in the kitchen the only two stoves that worked were the smallest ones..
So I have to say that all these things made it a bit uncomfortable and specially at bedtime.
Would not recommend specially if you are looking to rest at night and definitely not for 4 people.
Hope this helps for future improvements in the apartment.
