My boyfriend and I stayed in Rethimnon for 4 nights. It was an absolute delight staying in Costas apartments. Everything was as described. We arrived to the apartments at around 9am, Costas mother Maria greeted us joyfully with fresh baked treats and showed us to our room. Costa and his mother are super friendly, couldn't have made us feel more welcome! Any questions were answered quickly and clearly, Costa recommended us the restaurant next door which is honestly one of the best we've experienced in all of Europe. The apartment is situated in a really lovely area of Rethimnon just out of the town centre with plenty of gorgeous coast to explore and swim in. I highly recommend the Mamangakis apartments if you are staying in Rethimnon!
