Arta met me promptly at the apartment and explained how everything works. The apartment is in the perfect location in Riga- it's midway between the centre and the old town and in close proximity to great bars, cafes, and shops. The location is fairly quiet for being so central and the apartment was very clean and spacious. However, a few more kitchen utensils would be nice- i.e. more than one cutting knife, a few more kitchen towels, and some more glasses.
All in all, I had a great three-month stay! Thank you, Arta!
