I had a wonderful time staying at Hotel Capitol during my vacation time in Bucharest (Aug/Sep 2014). It is conveniently located very close to the University, Old city area, 10 minutes walk to the Parliament House. It is right at the city-center and just 2 minutes walk to the Metro, just 2 minutes walk to the old-city restaurants/bars area.
The Hotel staff are just wonderful, speak good English and very friendly. The manager was very helpful especially with me being new to their country. Among the reception staff, I especially would mention Liviu Gabriel, Adriana & Larisa as great folks who were very hospitable and made my stay a pleasant one! They will even book you a taxi for pick-up right at the front of the hotel!
The rooms are pretty clean, well maintained and the cleaning staff speak English too which makes it easy. I loved the soap dispensers at the hand-wash and right inside the bath tub!
One thing I would watch out for are the guys who walk around the hotel's vicinity trying to sell you 'exotic services'. Please be on the look out for them especially if you are a virtuous person.
Overall, I would strongly recommend this hotel as it is a great place for a competitive price and I will certainly go back to stay at this hotel the next time I visit Bucharest.
