My first stay in Toulouse. And I would stay at Odalys again should I return. It's far enough from the hustle and noise of the historic center. About 15 minutes walk to Place St Pierre where the action really begins, or 10 minutes from a metro station. 2 city bike stations with 300 meters, and the public shuttle from the airport is about 200m away, 15 minutes from the airport. Super convenient.
Comfy room, with kitchenette, microwave, plates and cooking ware, only thing missing is an iron and an iron board.
Good TV, good bed, good shower (i say : bring your own shampoo , trust....)
No maid service if you stay under a week, which i kinda liked.
