Dona 10 is a decent studio, but I don't think that I will be back. My issues with the place are threefold; first of all, you are unable to book a reformer Pilates class, though "forma" Pilates in all its misleading glory is available so that created some confusion. Secondly, Dona 10 (the location on Carrer Corsega) is quite out of the way of nearly anything that many would consider convenient (it is on the far left side of L'Eixample, several blocks away from Passeig de Gracia). Finally, while the instructor was incredibly sweet and friendly (and the rest of the staff polite and helpful enough) the class was, in my opinion, not nearly rigorous enough for it to be worth the money.
If you are looking for a moderate, calm session and don't mind being a bit out of the way Dona 10 is perfectly adequate, but for anybody with a taste for a little intensity and a more difficult workout I would try another spot. With that being said, I can only speak to the reformer classes, as they also have several other mat sessions which for all I know could be perfectly enjoyable. read more
