In our family vacations in Prague (2 adults and 2 kids), we stayed 2 nights in Art Suites Spalena from 13th to 15th June, the location of the apartments is great, just a 5 minutes walk to the metro station Národní trída. Cleaness and the conditions of the apartment were excellent, wifi works fine, etc, we really enjoy it . Also the apartment has heating, but in summer time the apartment realy needs air condition in order to be a 5 stars option.
