We stayed three nights at Santa's place (we were with my husband and two small kids). The communication with Santa and check-in were smooth, we followed the clear instructions. There are two separate rooms and a dining area in the apartment, spacious bathroom, fully-equipped kitchen, washing machine etc - everything what one might need even for a longer stay.
I loved how little touches were there: umbrellas, toothpaste and other small toiletries, activities for kids, even local beer in the fridge! We felt really welcome and at home:)
Santa recommended some great places in Riga. Kids enjoyed a huge playround just 10min walk from the house (away from the center, which means we most probably wouldn't have found it ourselves). The old town and the are with Jugend style architecture are just 10min walk as well. It was perfect for us and easily manageable for kids.
We are saving Santa's place for our future trips to Riga!
