Generally speaking Tania-Frankfurt is a good (if maybe basic) hotel in the middle of Bucharest, exceptional value for money. My room was a real gem with a living area separated from an upstairs bedroom via a spiral staircase, one of the most atmospheric I have stayed in anywhere. Staff are very friendly and most accommodating.
BUT, and this is a fairly big but, although the location is excellent in the general, right in the centre of the Old Town, the *specific* location comes with a significant drawback in that it happens to be adjacent to some of the loudest and most raucous clubs in the area. The pulsing music (at very high volume levels) doesn't end at night, generally speaking, until it's getting light again, round about 5:00 in the morning. They do have sound-deadening fittings, but this is plainly insufficient against such a volume level. Therefore I could not really recommend this for anyone who sleeps lightly - I can manage because I am one of those people who goes completely comatose, but a stay here would surely be misery for the type of person who wakes at the slightest peep. It's really a bit unfortunate, because other than this one issue there's nothing really to fault in what is otherwise a very enviable hotel.
