My first trip to Barbados was organized in the two weeks prior to the West Indies vs England Test match starting on March 22nd 2022. Hotels close to the ground were all full so I decided to book Marsh Mellow South Cottage through VRBO, although it was a few miles outside of Bridgetown where the cricket was.
The accommodation was exactly as advertised and the communication and help through BSL was first calls. I did have a few questions and the occasional minor issue but all were handled quickly and efficiently.
The accommodation was great for me, being on my own for this trip and would be excellent for a couple. The cottage is compact, but has everything you need and I slept well in the comfortable bed and a friendly neighborhood cockerel was my alarm call :-).
As for location you really do need a car. Walking to the beach would be a challenge even to the fitter people as the cottage is part way up a steep hill. Also, the essential stores are a short drive away in Holetown. Just to note, the the BSL representative organized the car rental for me. The car gave me the chance to explore the island but there are organized tours you could take also.
Overall, a great vacation, excellent accommodation, but you do need a car unless you want to spend a lot of money on taxi's.
