The good - the boat was nicely isolated on the river (i like this, others might not in Riga!) and we were able to sit and chat in the evening on the deck. It's a small boat so expect to squeeze in (as you should) and it was quite gentle weather to rest on. Best to stay with very close friends or family. It's a boat, it's not luxury, It's fun for that reason. Daniels comms were very good - although I was with a Latvian so had no idea what the instructions were - i figure these things out quick.
The bad - I have recommended that the bedding and interior are updated more often so that guests feel more comfortable and clean. The sheets were clean but the items themselves were dirty and stained.
Also that WiFi is not accurate as per listing on board but is available as public WiFi away from the boat.
These two reasons forced us to find other accommodation for the 2nd night of the trip as we required to work and sleep comfortably.
Overall - if its freshened up and maintained a little more its in a good quiet spot and would be a fun little stay for 1-2 close friends / people max - but only if you know what to expect on a smaller boat.
