We enjoyed our stay at Alex and Tanya's apartment. It is in a great location, very close to Old Town. The apartment was clean and had some unique features (skylights, a balcony, etc). Also, the TV had Netflix which was pretty great when we decided to have a quiet night in.
The only reason I would hesitate to recommend this apartment is the uncomfortable bed. It was the firmest mattress I've ever felt, and there were only two semi-flat pillows for our necks. I was concerned about hurting my back from sleeping on the bed. After first trying a night on the couch, I did end up sleeping in the bed for the rest of the stay but didn't sleep very well. Word of caution, if you need a softer bed or are prone to getting a back ache, this probably is not a good apartment for you.
