Our staying at Lisa's apartment was perfect. The apartment is 10 minutes walk to King' s cross. Check in was made using a code to enter in the house, and it was very easy and useful, since we arrived in the evening and we made everything by ourselves. The house was really nice and clean, really well furnished. We found everything we needed. You can sometimes hear the underground noise, but it is not disturbing at all and it's probably normal in Central London. Lisa was very kind and she answered to all my messages. I will come back for sure!
