High ceilings in a classic building close to (but, thankfully, not in the thick of) Old Riga, and easy access to the Central Market and train station. The flat was everything we needed to explore Riga from, and was a nice environment to fight off the jet lag from and prepare a few meals in, as well. Beside the beautiful building, not too many over-the-top frills, but certainly a clean and professional place to stay, and a very professional host.
For those who hope to travel light, the flat is equipped (in-unit) with a new washer/dryer, which we were happy to be able to take advantage of during our stay. One item to flag is that a couple of the fun bars are just outside the gate of the courtyard the flat sits in, meaning (1) it's easy to go out and have fun, but (2) there is some late-night noise that at least during the summer months, you'll get coming into the apartment.
We feel like we made a great choice with Christoffer's flat!
