Stayed for 5 nights, 15 minute walk from train station. Room was pleasant, big windows, good shower, comfy beds. No lift & being situated on 5th floor was hard going, they kindly offered another room, the only one available was on the 4th- but I took it. Breakfast was a farce. Day one was directed to SOU100 (?) and (as vegetarians) was served a plate full of cold meat and stale cheese by an awful & attitudal woman, who made us feel very 'in the way'. No choices. Had emailed & requested weeks prior. Day 2, received a ham & cheese sandwich in a bag at the reception desk, staying they couldn't provide the veg options... Surely just don't put the ham in the sandwich?! Day 3, didn't even receive that. Nothing. Found a beautiful little cafe just down the street called Mist Coffee, and didn't look back.
Besides the farcical breakfast scenario, had a pleasant stay in Prague Pensions, slept well, good location with trams, bars, fooderies, & shops all local.
