The entire process from the reservation (including a spontaneaous extension of the stay) to finding the appartment and the stay itself was very nice. Martin responded very quickly to my messages and we felt very much at home in the appartment. The very central location was ideal and given the fact that there were the gates around the appartment complex, the place was also very calm.
It is highly recommendable and I am sure that next time I will be in Riga I will try once again to stay in Martin's flat.
