I stayed in Emily's Suite 3 for six nights with my 9-year-old daughter. I already knew the area fairly well and chose to stay, in part, because I recognized the value of this flat and the perfect location for a stay in London. Belsize Park has everything that you need for daily life (grocery, restaurants, chemist), and it's so convenient to the rest of London without having to deal with the crowds of the city center. (As an academic, I'll also note that this would be ideal for those wishing to research at the British Library, BL's Newspaper Library, and many other archives in the area.) We were allowed to check in a bit early and, prior to our arrival, Emily's communication was excellent. I booked a few months in advance, and she followed up right away with info about the area and the accommodations--she then followed up again about two weeks ahead of our booking. I was able to meet her upon check-in, as well as her property manager. Emily is friendly and accommodating. While I had not asked, they offered an inflatable mattress for my daughter, which was great, since she was tired of sharing up with me after more than a week of travel. The neighborhood is quiet and safe--rows of 19th-century terraces sporting stained-glass windows and carved trimmings. The flat is lovely--as pictured--and we made good use of the kitchen, which is important for the sake of economy and when traveling with a child. Emily had left us some milk, cold water, and candy in the fridge, which was lovely. We did not see much of the manager after check-in, but we didn't need any assistance and knew that we could locate him easily if necessary. The noise level within the building was low--I could hear people in the foyer only occasionally and someone's TV only on one evening. Other guests were considerate. The kitchen and living area were quite clean, although the bathroom was a little less clean than I would have liked (the shower, sink, toilet were all perfectly clean, but the floors and baseboards could use some detailing). That said, I have read some reviews in which the bathroom is cited as an issue due to its age, but it was up to general standards for me. The shower had good water pressure, which seasoned travelers will probably appreciate knowing! I would stay in this or any of Emily's flats and recommend them to others without hesitation.
