This morning, I signed up for HomeExchange.com. This is listed as one of the oldest and best home exchange sites on the net. Starting with a 14-day free trial, we intend to keep it going. Some of our friends have had amazingly positive results and not one negative one.
The funny thing is, 2 hours after I completed the copious pages of the profile, I received an e-mail from another member. He is from the Canary Islands and loves Budapest. He and his 3 friends are in their 50s and 60s. His place looked gorgeous. They wanted an exchange for mid-June to mid-July. Unfortantely, I have university obligations as well as B and B guests during that time.
This does bode well for the future. The next step is to register with house-sitting sites.
