This is our second time staying in the Gothic quarter in Barcelona and our first time at the Mercer. We loved the hotel and the location was perfect for our wandering.
The only negatives about the hotel were the access to taxis is hard and the shower was odd. But otherwise we loved it.
The biggest highlight for us was the restaurants. The breakfast was great, the tapas place in front was great and the restaurant for dinner was the best meal we had on our trip. Highly recommended!
