Eva and Darney are absolutely fantastic hosts. Darney met us and showed us around the beautiful apartment, and gave us several great recommendations for restaurants and markets nearby. They went above and beyond when I realized I left some items behind, and they immediately mailed the items to me in the US.
The location of the apartment is amazing, and it's very easy to get to major tourist sites from here. There is a delicious bakery downstairs (LeFournet) and several grocery stores nearby. Las Ramblas is about a 25 minute walk and there are many restaurants along the way.
