You're not going to get a better deal in Lagos at this price point! The location is amazing, the staff is extremely helpful when they are available, the room is really spacious and even has a little kitchen/dining area, and overall it was an awesome experience and we would absolutely stay here again!
That said, there are a few things to keep in mind: Lagos Center Studios has the same owners as Inn Seventies, and even though our reservation was for a room in Center Studios, we wound up with a room in Inn Seventies. That said, the locations are super close and the room we had at Inn Seventies was awesome and had all the amenities we would've had in the other spot, and a better view, so we were really happy with the change!
Checking in is a bit tricky as others have said--you check in at Inn Seventies at reception, which is on the top floor. Expedia said check-in started at 2 but it actually started at 3, and we were initially turned away and told check in wasn't there by a maintenance worker, which was a bit confusing, but once hotel staff arrived, they invited us to sit for a drink at the rooftop bar (which is a great spot with a great view, albeit pretty loud music), while we waited, which worked perfectly.
Also worth noting, there's another Inn At Seventies which is FAR out of town, and it’s hard for GPS/Uber to get the right address. I suggest searching for Sky Bar in Lagos, which is the same location as Inn Seventies, but doesn’t have any weird other locations in GPS.
