Rick,
I know exactly where Dave was staying as I introduced him to the apartment owner - a chap called Jaime (pronounced himee hence the different spelling). The apartments were owned by Jaime & his wife Maria who also owned Jardin Suiso - the restaurant.
Dave moved from there just a little while after your visit (just over 18 months ago!!) & although I have seen him in the street just a couple of times since then, I have no idea where he is staying. As he has not been in touch with us nor given us any new address when we have met, we think he may not want to remain in contact with 'Gringos' per se & we have therefore not tried to find HIM. If he needs us, he knows out number! ~ Grahame.
