It is a nice place, clean, modern and enough room for at least 4 people. More than that, it would be really crowded, especially if most of the party are adults. It was in a central location, close to trains to get around London. However, if you order an Uber, sometimes the drivers cannot find this place and you would have to walk to the corner store for them to find you.
I never communicated with Zuzana, she has another manager, Gustavo who interacted on her behalf. All of our communications were by email or text so you may never meet your hosts in person. Overall, it was a fairly business-like transaction and Gustavo was very responsive to questions and will get back to you timely.
