Phraeksa is treated here as Phraek Sa, BTS Sukhumvit Line station E21 in Samut Prakan. MRTA places the station on the elevated Bearing - Samut Prakan Green Line extension, opened on 6 December 2018, and the BTS route map lists Phraek Sa on the Sukhumvit Line. The station sits south of Srinagarindra and north of Sai Luat, serving a retail-heavy section of Sukhumvit Road with direct rail access to Pak Nam, Samrong, Bang Na, Asok and Siam.

The station's strongest practical anchors are retail, schools and healthcare. OSM/Overpass identifies Robinson Lifestyle Samut Prakan, Big C, Lotus's, Paolo Memorial Hospital Samutprakan, Samut Prakan Hospital, Mueang Samut Hospital, Samut Prakarn School, Satri Samut Prakan School, Praphamontree 2 School, Pom Peek Ka Park and several local markets. Public sources also describe the station as being next to Robinson Lifestyle and Big C, which matches the OSM retail cluster.

For property, Phraek Sa is a value-and-convenience station rather than a premium Bangkok address. Condos and townhomes nearby can suit commuters, local workers and families who want mall access, supermarkets, hospitals and schools while staying on the Green Line. Buyers should check the real walking route to the BTS, Sukhumvit traffic, noise, flood exposure, building age, parking and whether the project is closer to the retail cluster or set back in a less walkable residential pocket.
