I have spent a week in this apartment and have enjoyed it greatly. Quiet place with easy way of getting to the center of the city. (The bus goes 2-3 times every hour and the taxi is around 3-4 euros) There is also a big shopping centre more or less close to the apartment (20 minute walk) with a big shop and a few places to eat. (LIDO is great, make sure to visit it at least once)
I haven't had a chance to meet Solvita but Claus was a very hospitable host and helped me with any questions I've had.
