I stayed in Ulises' studio for 3 weeks and it was just great. The studio is very clean, neat and centrally located. The photos and description describe the studio very well. You have everything you need both in the studio as right outside of it. Plus, you get free, daily workouts as you have to take the stairs.
When I got to the studio, Ulises was there to welcome me, and when I left, he was there to say goodbye. Ulises is very helpful and flexible and thus a very good host. You won't regret staying in this studio :)
