Perfectly clean, Perfect location - easy to get from the airport by public transport. It's right in the old city, very atmospheric streets, beautiful. A small thing - they do not provide towels, so bring your own or there is a market nearby where you can get ones for really cheap.
The apartment has everything for comfortable short or long-term living. Supermarket, bars and everything you might need is nearby. Highly recommended, I will book this flat next time in Riga.
