27 yo software engineer with an awesome Labrador looking for a flat or room

I'm from Chile, 27 years old, I work as a software engineer and I have a super friendly Labrador dog. I'm looking to share a flat with 1-2 people and have my own impassable room. I won't expect necessarily to be my best friends but to be able to have proper communication and not being cold. I play basketball, go to the gym and walk my dog, and my flatmates would be  welcomed to join me in those activities. My favourite location would be Vinohrady, but I'm open to more location as long as they are in or near the center.
