Canggu is the other "beach spot", however is far from being a nice and sandy beach. It's more for surfers, with some serious waves.
Dojo Bali is a nice coworking space equipped with all the amenities. They also have a pool, outdoor seating and a beach nearby. They have reliable and fast Wi-Fi with speed ranging from 25-80mbps.
Right next to the Echo beach. They have fibre optic internet, a pool, Skype booths, gardens and conference rooms. Dojo Canggu also has a nice cafe with fresh fruit smoothies.
A 2 bedroom villa with a pool costed about $1200! You can get a sim from Denpasar airport. I paid about $14 for 30 GB of data for an XL sim, so sims are pretty cheap too. Rou Coffee and co-working was my favourite work spot with fast WiFi and no membership fee.
Located in Canggu, it is my favourite and the most Digital Nomad friendly WiFi cafe in entire Bali. They have great WiFi, power sockets, an awesome ambiance and is 250m from a surf beach! Really nice place to get some work done. I generally do all my remote work out of this nice cafe.
