Petra has a lovely and comfortable home. It is really well located within a neighborhood that has many great services, beautiful parks and several transit options. We were able to stay in the neighborhood and explore all day or quickly hop on a bus or tube to get almost anywhere quickly. The nice little back yard with a pergola, grill, apple tree and trampoline makes for a nice little oasis after a day of running around. One thing to consider if you'd like to stay at Petra's is that it's in a part of London that is lively, so expect to hear the hum of the city and the occasional reveler late into the night.
Petra herself is an excellent host and responded quickly to our needs if there was a hiccup with the an appliance or we needed to know where to get the best kabobs.
