Blanka and her family are welcoming, friendly and responsive hosts. Had a comfortable month-long stay at their place, felt at home and enjoyed talking to members of the host family, they are quite educated and pleasant people.
The house is spacious and quiet, despite being located on the rather busy Colney Hatch lane. The room is located on the first floor, has a window overlooking the garden and is large enough to allow working from home from time to time. There is a kettle, cups and cutlery in the room and you can use the fridge in the kitchen to store your food and a microwave/oven to cook them. Unfortunately, there is no dining room, meaning that eating outside your room is not an option and making it a bit harder to socialize with the host family. The bed is a sofa bed, not be the best choice for those with spine issues, the room is a bit rundown and it can get cold at night due to the wooden window frames, but it's all tolerable, the price is reasonable and it's still good value for the money.
The location is nice: Alexandra Palace and Muswell Hill is nearby, and it's a pleasant residential area with picturesque views. Aside from that, there are several forests nearby, good choice for the morning jog. The bust stop is right in front of the main door, which is very convenient. The nearest tube station, however, is quite far away, but is still easily reachable by bus. In general, daily commuting to central London is doable: bus 134 takes you straight to Euston Square in about an hour.
Overall, had a nice experience and would recommend for short stays, especially work-related (like internships etc).
