Andrei's apartment is in a perfect location - minutes from the train station, underground and tram stops. There are three supermarkets within a five minute walk, and you're about 10 minutes from the Old Town.
The apartment itself is really comfortable, everything you could want is there - dishwasher, wifi, coffee-maker etc.
There are maps and guides, and Andrei himself is full of useful local information! He was flexible with checking in and out times, and I would recommend a stay here any time!
