I had a great time at Gail's place, where I stayed almost 10 days. She is very nice, friendly, helpful, uncomplicated and open, her cat is also lovely. Gail was very flexible to let my boyfriend stayed with me at her flat over the weekend what saved us time and money.
The flat is very central, cosy and well decorated, internet worked always perfectly and I always felt safe in the neighborhood. King's Cross/St. Pancras is 10-15 minutes walk from her place, but you can also take the bus, that stops around the corner if you don't feel like walking. She always asked me how I felt and if I needed anything - she also gave me recommendations on what to do in London or where to go.
The last day I was there, she saw that my luggage was pretty heavy from shopping in London and I was running out of time for the airport and she was so nice to take me to Paddington Station where I could take the Heathrow Express directly. Thank you very much for that and for the nice time at your place! I recommend Gail's place to anyone who wants to visit London, she is a great host.
