Riki's place in Prague has to be one of the best places we stayed in Europe so far. Awesome sized apartment, very secure, and in a perfect location. Great bars and food within minutes of all directions, and 10-15 mins leisurely walk to Prague old town. The timeliness of the check/out was perfect and they were very accommodating for our late arrival (6pm). Perfect place for up to 4 people (2 couples) with two separate toilets but a common bathroom (ensuite) off the main bedroom. Additionally the Metro stop on Line A just around the corner is only two or three stops from Prague Castle.
If I return to Prague this is the ONLY place I'd stay again.
