I stayed almost three weeks in Daniela's 'ateliér' and considered it perfect for a solo/work traveller. A small refridgerator, microwave oven, kettle and a toaster where perfectly enough for my needs. I especially liked the central but quite location. The castle area, Nerudová street, and Petrín hill are all just around the corner, but more importantly (at least for me), there's also a relatively short walk to Letná and other parks.
