We stayed in the appartement for three nights. We arriverd earlier than was possible for him to welcome us, but Nacim really helped us by enabling us to pick up the keys at a friend of his, so that we could drop our bags early.
The room is quite small, but with two people it was okay. The location was perfect! You do share the house with Nacim and (possibly) two other tourist couples though (which in our case was no problem). One small point of improval: the house is quite noisy, so earplugs might be useful for sleeping.
Overall we had three good nights, so thanks Nacim!
