I highly recommend staying with Teresa and John. Their home is lovely and very conveniently located only a short walk from the Arsenal underground station. Teresa and John were great hosts, truly making us feel like we were guests in their home. We enjoyed getting to know them over breakfast, which included homemade bread and jam made by Teresa. Although there were other guests staying in the other room upstairs, the room still felt private enough and had everything that we needed for our stay. The shared bathroom was kept very clean.
