Gerda’s flat was perfect for our family of 4. There is a king bed and a sofa bed. The kitchen and bathroom are good sized. There were lot of towels and sheets, soap and shampoo that the host provided. There is no fan provided for hot weather. The windows can be opened for cooler air at night, but the flat is on ground floor and close to a main road. So we did not leave it open at night. The flat is close to many eating places making it very convinient. It is about 3 miles from St. Pancras station. There is a closed patio (with furniture) in the backyard. We didnt get to use it as we stayed overnight.
I highly recommend the place.
