This was our second cruise with Emerald Waterways (the first being the Douro river cruise which was also excellent).
We booked a cabin on the lower deck. The room was well equipped, comfortable with plenty of storage space. The furnishings were of a good standard with no room for complaint. The only downside of using cabins on the lower floor is reduced natural daylight. Something we were aware of because of our previous cruise with Emerald. So little time is spent in the cabin that this was never a problem.
The ship was well maintained, with all communal areas being kept in a highly presentable state.
