I have nothing but praise to say about Nky, but let's first talk about the place. I stayed here for 3 months. It's a wonderful house in a pretty peaceful street. For longer stays, you have a supermarket in a 10-15 minute walk, and a little shop with daily necessities in a 5 minute walk. Although it's a little far from the city center, you have both a direct bus and a tube near the place, so it's well connected.
As for Nky, she is a wonderful host. She always made sure I (and the other tenant) were as comfortable as possible, above herself. Near the beginning of my stay the heater malfunctioned (it's already repaired), and she gave us a floor heater, which she only had two, so she basically froze the couple of days we were without it. One thing to note is taht she has house rules. It's nothing crazy: not putting the frying pan and the kitchen knives when used on the dishwasher, because they can get damaged, things like this. This is explained when you arrive and in a folder in the room. If you do it one time because you did not know, she will warn you but not fault you. If you keep doing it, it's on you. I felt the need to write this last part due to a comment left on the other room Nky offers. All the points this tenant make are simply wrong.
Overall, I highly recommend this place. Good neighborhood and a wonderful host.
