We choose Uniworld based on their reputation as a 5 or 6 star line. of the 13 day cruise from Lisbon to Madrid, we were on the ship 8 nights and the other nights in very nice hotels.
The overall experience was good, worst part of the cruise was on the ship.
They were VERY understaffed and they kept saying the air conditioning was being fixed, however it NEVR worked the entire time!! Extremely uncomfortable in the lounge and dining room!!!
