Overall we (a couple) did not really enjoy our stay in Helenas apartment and would not recommend it if you are looking for a comfortable, cozy apartment were you can feel like being home.
In our opinion, the pictures communicate coziness, but if you are in the apartment, you can not feel this. The apartment is rather a whole floor - which is good if you are a lot of people staying there....
Additionally, if you come to Lagos only for party and visiting beaches and planning just on sleeping in the apartment and staying away the rest of the time: perfect! It is located directly in the city center and proportionally calm. So you can reach everything important (restaurants, bars, supermarket, beaches) by foot.
We on the opposite, we wanted to feel like being home, to use the kitchen and enjoy the evenings on the (small) balcony. But the apartment did not seem to be clean and we did not want to use anything in the closets of the kitchen.
Concerning communication with Helena: simply not existing!
Overall, compared to other airbnb hosts, who care for their apartment and customers, this is just an apartment to make money! And you can feel this in every room and in contact with Helena.
