Flavio F., 2020 on Trustpilot
“I chose my windows at the Spazio Casa studio in Nicosia. Finstral products were recommended to me and I relied on them. I don't regret my decision: the windows are of high quality, durable and provide good insulation. I live on a busy road, but I can't hear any noise. Really a very good product. I am grateful to the salespeople for their recommendations and the installers for the efficient installation. I can only warmly recommend Finstral.”
Fillippo V., 2022 on Trustpilot
“From the very first conversation, I had a good feeling about the Finstral staff. They were transparent about delivery times and proactively thought of solutions, including financing. [...] The installation was carried out smoothly by two friendly, pleasant and particularly competent employees.”
