This was the first time we tested the Bal Harbour area when traveling to Miami Beach : it has proven a total success.
The property is as advertised (yes, as good as on the pictures!). On Collins, 3 blocks from the beach. 6 from Haulover inlet and park.
We usually use a car and travel, so parking on the premises is a necessity, satisfied in this case. Location, in this regard, is also a plus, as reaching the continent is easy both through the bay as from Hollywood/aventura minutes up North. Both FLL and MIA airports are within 35 minutes. The terrace is wonderful : we cooked every night in the apartment. We were traveling with my wife, just the 2 of us, and equipment was plentiful. I would recommend the apartment without a doubt for a party of 4 (each using one of the main rooms and separate bathrooms) - more guests would be too much in my appreciation but it is a totally subjective comment...
Communication with the owner and access procedure were responsive, fluid, hassle free. We would come back as soon as possible.
PD: part of our stay was during Memorial day week end, and Miami was hell... But the area remained totally quiet and tranquil.
