This is one of the most thought-out accomodations I've ever stayed at. It was very clean, with all the amenties you can expect, from aluminum foil to iron and from dishwasher to detergent. I didn't really have to buy anything other than food and it was important since we were travelling with kids. The location is superb. Calle Montecarlo is a short dead end road which has access to the trail along the seashore which connects San Feliu beach with Sant Pol beach. The views from the trail are fantastic. You can spot the sea from the large terrace of the apartment as well.
I would strongly recommend having a car because shops, beaches and restaurants are not that close.
For me it's the best part of Costa Brava. It's not about long spacious beaches with many bars and night clubs but rather quiet and beatiful nature.
We had some issues with wifi but I think Mark finally fixed it.
