Mercé is a nice hotel, and we had a great stay. The rooms are a bit dated but you have everything you need, and they are kept clean. The nicer looking rooms shown in Hotel.com's pictures are the more exclusive rooms, which you can upgrade to, for €30 per night per person. The upstairs pool area is nice, and the breakfast in the restaurant was good and with a huge selection. The hotel arranges different entertainment in the rooftop bar and especially the Saturday Rock Night was great!!!
Pineda de Mar is a nice little town with bars, restaurants and shops a short walk from the hotel. The beach is just wonderful, and it is easy to take a train down to Barcelona.
