Lagos Hotel
Your best bet would be The Sheraton in Ikeja or The Protea on Issac John Street also in Ikeja.
Neither are at the airport so you would have to arrange a pick up via the hotel from the airport. I haven't been to Lagos for just over a year so there may be some slight changes.
Other than that pay the extra and stick with recognised brands to save yourself plenty stress?
PM for any other info!
