I had a long-term stay at the Windsor pad and was very happy there. The apartment was a good size for one person or a couple. It looks even nicer in person than the pictures, it's clean and everything you could need was supplied. The bed is literally the most comfortable thing ever.
The courtyard was great for my two dogs, very secure, and there were a lot of great parks nearby for them to run around. The area is lively and close to shops, restaurants and transport.
Saskia herself was a great hostess. She is very knowledgeable about the area and answered any questions or issues that I had very quickly.
I wouldn't hesitate to recommend this apartment.
