We were five people during a weekend in Riga. Location and check in with the lock box was perfect and the flat is suitable for about 5 or 6 people.
We gave the experience a four star rating, due to the lack of shower curtain in the bathroom and limited utensils in the kitchen, as some of the reviews from other guests are describing. We tried making breakfast the first day but ended up eating your for all our meals the rest of our stay, unfortunately. Other that that, we still enjoyed our stay in Riga.
