I took my little sister to London for her birthday and staying at Catia's was a blessing! She and her husband are wonderful hosts and just made everything so much easier so we had nothing to worry about except go out and enjoy the city.
Her place is very close to a tram stop so very easy to get around Croydon area and the trains to the airport and the city.
All in all our stay was a very pleasant one mostly thanks to the hosts.
