Excellent hotel, and great value for money too. Good central location and helpful staff. Has everything you could ask for city break - hot and cold breakfast buffet, restaurant and bar, tea and coffee facilities, minibar, complementary toiletries, Wi-Fi, safe, AC, etc.
Prague is a big city so expect a 20 minute walk to Old Town, but it’s simple and easy to navigate, or Uber for next to nothing. Maybe not 4* by British standards but certainly above average for Eastern Europe. Would happily stay here again or recommend to others.
