American expats Lance and David opened Casa Cool Beans in 2010, determined to raise the bar for accommodations in Rio, and their guests' raves about the attentive service, chill atmosphere, and gorgeous decor testify to their success. There's not a leaf out of place or a speck of dirt to be seen, and Lance, David, and Sergio, the manager, go out of their way to provide tips and touring advice. The converted colonial mansion, painted a resplendent purple, is set over three floors separated by leafy outdoor spaces complete with sundecks. The rooms are tastefully appointed and decorated with artworks (many of them available for sale) by gifted local artists, and bathrooms are stocked with quality Granado toiletries. The pool has views over the scenic, bohemian Santa Teresa neighborhood, where many of the artists live. The lavish alfresco breakfasts are a high point of a stay here. The guesthouse can arrange private airport pickup (R$180); nighttime arrivals are required to use this service. Note that they have a no-under-18s policy.
