Eli & Agus's Eixample apartment was perfect for our family of four (mom/dad/2 teen boys). It was a WONDERFUL balance of being in a safe, quiet, and resource-rich neighborhood -- with loads of restaurants/tapas, shops, and groceries -- as well as being near all the sights you need -- the subway at Sant Antoni was a direct line to Sagrada Familia, the Museu Picasso is a 30-min walk through interesting streets full of shops, the subway/train station at Placa d'Espanya whisked us away for a day trip to Montserrat, and it's a quick walk to the MNAC and Montjuic!
But another favorite part of our Barcelona stay was staying in! Eli & Agus's place has:
1) A surprising amount of space -- we all could relax together or even apart from each other
2) Quiet at night so we could rest up for a new day.
3) A great washing machine, a dishwasher, and -- most importantly for my husband -- AC!
Eli & Agus were easy to communicate with and their colleague Ivan met us for a swift and simple check-in, with lots of tips to help us get around and choose what to do. We would recommend Eli & Agus's place to anyone.
