Kristine met us at the apartment and was very welcoming and friendly. The apartment is located in the old town, everything was walkable and was only a 2 minute walk to one of the main squares in Riga.
The cave itself was as shown in the pictures, it was a little hard to adjust to the lack of light but obviously we expected that because of it being a cave! We would recommend taking some jumpers with you, it is a little cold and damp in the cave. There wasn't enough hot water in the tank for both of us to take a shower so maybe bare that in mind too and make it short!
The apartment has a real novelty factor and Kristine's communication was fantastic all throughout, overall we would recommend Kristine's apartment!
