We are very glad that you were able to access the apartment with the instructions provided by us and without further assistance. We did provide detailed information to assist you on arrival including pictures of the building and the access details and remained available till late in the evening, long after your expected arrival. Once your arrival was later than expected we became concerned and tried repeatedly to reach you on your number provided without success. We do not know how else we could have assisted you, however we are very sorry that the detailed information and attempts to reach you weren't sufficient for you on this occasion. We are very glad you enjoyed your stay and appreciate you noting our flexibility in respect of your requested late arrival, the high quality, cleanliness and spaciousness of your lodging and the exceptional pricing provided at this level of accommodation for the three in season nights in London. We do hope you choose to stay with us again soon.
