I loved Mark's place. The view is amazing and the place is well equipped. The A/C worked well since it was hot (25 degrees) in Lloret de Mar even in mid October. I really appreciated that the host left milk for the coffee, and filters for the coffee maker - those are often my first purchases at an AirBnB so very thoughtful to have provided these. There also was a bottle of sparkling wine and chocolates which were a real treat.
Other reviewers have mentioned that the checkin could be improved, and I agree. Belen, who is apparently Mark's agent on site in Lloret, was great -- once I found her. Just know that if you are driving and need to drop bags, you will probably have to park illegally for a bit to unload bags - there just is not really much legal parking near the apartment (this is because it is in such a fantastic location, right on the beach!) I figured it out despite speaking only English and Belen was a real sport working through the language barrier.
One other minor problem was the bathroom - there is some problem with the shower drain that seems to cause a bad odor in the bathroom. I think to partly mitigate this, the drain is covered with a yellow washcloth. I stupidly didn't remove that when I first took a shower and so had water backup and leak ALL OVER the tile bathroom floor - dangerous. Be sure to remove the yellow cloth when using the shower!
I loved being able to walk everywhere, including the beach across the street, and recommend El Gaucho (3 blocks away) for great steak, Cafe de la Vila for pizza, and Granier (just around the corner) for breakfast. I really enjoyed my first visit to Lloret de Mar!
