Just returned from 3 nights in Prague and thought the Bohemia Plaza represented excellent value for money. Whilst an attic apartment, it was more than adequate for our needs - nice to have a fridge and kettle, so you can keep drinks cool, make a cup of tea etc.
Spotlessly clean when we arrived and room serviced daily. It was nice to have 2 duvets (big double bed), plus a radiator that you could regulate.
Breakfast was great - cold meats, cheeses etc, plus small offering of hot choices including scrambled eggs, bacon and spicy sausages.
Location wise, about 10 minutes from Wenceslas Square. If we were to visit Prague again, we would certainly return to the Bohemia Plaza!
