We arrived in Roses, Spain without a reservation during peak holiday season. Luckily, we were able to get a room at Rosamar. We were only there for 3 days but it turned out to be quite nice. The hotel was modern and located only a couple of blocks from the beach with many restaurants, stores & an internet cafe along the way. We'd taken a taxi from the bus station to the hotel for about $10 euros.
The staff was unbelievably friendly - front desk clerks all offered info on how to get places and were ALWAYS in a good mood. The cleaning lady was also cheerful and also answered questions for us. And the restaurant staff was also helpful.
Our room was very clean but really tiny. It was the smallest hotel room we'd ever been in. But we booked it at the last minute so we basically got what was left over. And there was a lovely balcony in our room overlooking the pool that saved us from clausterphobia. The walls were a bit thin too. It had a strong a/c unit that helped beat the heat. The bed was comfortable. And the free wi-fi was great (not many hotels in Spain/France have it available for free).
I would recommend this hotel to anyone with children or couples. It was a great place to stay - just ask for a large room.
