Hotels in the Old City and surroundings:
The area marked in a red frame is the old city. The blue area is the fountain square, Nizami street and surrounding streets where you'll see only old and architectural buildings of late 19th - early 20th centuries. The boulevard (green frame) and Maiden Tower (yellow frame) are marked for orientation only. I can't recommend which hotel exactly to choose in this area, because as a local I never had to stay in any of them. Booking.com has "reviews" option which may help you make the right decision.

Three Avenues to witness early Soviet Architecture:
The staring point is Hyatt Hotel nearby Bakhikanov bridge. From there you can take a cab (5-10 AZN at most for the whole ride back to downtown) or the bus number 95 (makes a small turn between Inshaatchilar and H.Javid avenues / you'll waste about 5 minutes). If you decide to walk, the whole path will take about 30 minutes to reach the end of Parliament avenue (mountainous park). If you do take a walk, you can return back to downtown from the ending point of Parliament avenue via bus number 95 or 18 (bus stop mark - yellow dot) or take a funicular ride in the mountainous park (yellow dot again / funicular ride is still free). If you decide to walk from there to downtown, just walk downwards by the road after a turn to the left (you'll see a stone plated road soon). It leads right to the downtown (15 minute walk distance).
