My husband, son (3.5 yrs old), and I stayed here for 5 nights and it was perfect! Magda and John were very responsive in the planning process and even though we arrived later in the evening, John was there waiting for us and quickly gave us the run of the place. John was also very responsive when we contacted him the first day to figure out how to turn down the heat (which was very easy!). The flat was very clean, nicely updated, and best of all, had everything we needed to make our stay easy.
Probably the best part is the location. We were close to two tube stops that were convenient for everywhere we wanted to go. We were also able to walk to fun neighborhoods, parks, shopping, etc. We highly recommend the apartment and Magda and John!
