We stayed for 5 nights, enjoyed the hostel and Bogota. Candelos is situated in the old city, close to transmileno station Las Aguas, short walk to banks, museums, shops and bars. Plenty of cafes and restaurants in the area also.
Staff are friendly and helpful, most speak decent english. Wifi is good and hostel has 24h reception and a beer fridge. Also breakfast is a couple eggs, bread and a coffee.
Also recommend to take the free experience walking tour around the city, guide is informative and speaks great english! Enjoy
