YES. Even the most skeptical are extremely satisfied with this method, and long term results are exactly the same. As
long as you have
access to the internet, you can have lessons from the
comfort of your home, with no need to worry about coordinating travel, etc.
In fact, it's our opinion that online lessons work BETTER. Aside from the increased comfort and convenience, you can look straight ahead and see what your instructor is drawing on screen and simultaneously converse face-to-face. This is impractical when in the same room, since working on a table means the sheet is upside-down for one person, awkwardly straining your neck, etc.
Give online lessons a try - you won't regret it.
