“Superb”
04 Jul 2025
We had a wonderful stay! The 2-bedroom apartment was clean, spacious, and perfect for our family. The beds were super comfortable, and the kitchen had everything we needed. Great location, close to shops and transport. Highly recommend!

“Best place we stayed in our Europe 6 weeks travel.”
23 May 2025
An absolute standout among all the places we’ve stayed during our 6-week European journey. The apartment was exceptionally spacious, with a sleek, modern design that made us feel right at home — we genuinely could have lived there permanently. The sofa bed was, without question, the most comfortable we’ve encountered in Europe. The staff were warm, welcoming, and incredibly accommodating, going above and beyond to ensure our stay was seamless. We especially appreciated the thoughtful touches like complimentary still and sparkling water. Everything was spotless, and the added convenience of secure lockers for our late check-out — provided at no cost — was a game-changer. Truly one of the best stays we’ve experienced. Highly recommended.
