As others have mentioned, the parking on the -3 level of a nearby garage is very tight to get into. You'll need someone to help negotiate the ramps without hitting the wall. However, it's worth the effort as the alternative is to pay around €30 a day in the public car park. It seems there's hardly any free parking in Cadaques. The hotel did say we can park on the street nearby, but not on Mondays as there is a market.
Our double room was clean and comfortable. Not huge, but for the price you can't complain, and it had a small balcony. Breakfast was a selection of fruit and pastries. Staff very friendly and helpful, and we were able to leave our luggage and car parked for the whole day after checking out.
