Yes; friends recommend Colibri or Alesie just about 1 mile from the centre of Las Terrenas.
Other hotels are good in the area also including the All inclusives. Many are smaller than the major resorts in the PP Sosua Cabarete area.

I have met groups of guests staying at Portillo and they have seemed well pleased.
