We were in Lantana 8 in January 2016 for two weeks. The unit is very well positioned on the property - steps to the pool, western exposure. The condo itself is well equipped and comfortable, and we didn't notice any noise between units. This unit was in the building closest to the beach, which was only a short walk away. The grounds are well groomed with lovely gardens. The building is secure and we always felt safe.
The property is located a few minutes north of Holetown, easily accessible on the bus (the bus stop is just steps from the condo). The buses are a very inexpensive way to explore the island, but can be a bit hair-raising with some interesting driving (yellow buses, especially). There are lots of buses though, so if you want a seat and slower ride, wait for a blue bus (government operated). There are a number of super restaurants in Holetown, and the grocery store (Massy Superstore) was perfect for groceries and dry goods.
The condo is close to the road, which can be loud throughout the day but it gets very quiet at night. Likewise, the condo is adjacent to a primary school so there can be a lot of noise during recess and lunch, and at the end of the school day. None of this bothered us - we were out and about most days, and for those days we relaxed around the pool, we just considered it the sound of daily life.
One of the units in the building was under renovation - and although we realize this was not the fault of the condo owner, the hammering and knocking was annoying and chased us from the condo for a couple of days.
All in all we had a wonderful vacation and would recommend this condo for anyone wishing to visit Barbados and go at their own pace. As mentioned, be prepared for a bit of noise.
