We have rented an apartment. It was just next to Charles Bridge old town and perfect for a family.
Apartment was large and newly refurbished, with modern twist, very large comfortable bed and sofa bed.
On one side, it was a great location. When you were tired, you just pop in for a rest. But the downside, at night it got bit noisy from the pub.
But overall, affordable luxury in the centre of Prague. G
Cannot get any better.
