There are two Avilas - Avila South and Avila North.
Neither have balconies (hence, lower price) - there are enclosed spaces like large bay windows instead; there is no covered parking (which is not uncommon in FL). Avila South has no lease the 1st year, while Avila North is ok to lease right away.
Proximity to the beach is similar.
Avila North has several buildings in the complex with a clubhouse and a pool.
Avila South has a nice fitness room and a pool as well.
Avila is one of the cheapest condominiums in Sunny Isles Beach, and is popular with renters/pied-a-terres' dwellers.
Hope this helps,
