We have spent 4 nights at Kent's place. Although we never got to meet him, he was more than helpful over emails. We met the housekeeper and she was very welcoming and helpful as well.
The beds and the sofa bed are very comfy and the house is very clean, with everything we needed.
The location is great, a 30min walk to the city centre or 5min walk to the nearest tram or metro station, with mini markets nearby.
The only 2 negative things I thought I had to mention, but never a big issue, were that we couldn't use both showers at the same time, as the hot water was affected by it, and that 2 of my friends got their hair sucked by the hairdryer. That was quite unusual.
Other than that, it was a very pleasant experience and Prague is absolutely amazing.
Thanks.
