Eloy and Maria's place is modern and well-designed. It has everything we needed and more for our stay in Barcelona. We had plenty of space for 2 adults and one child. We cooked some meals in the kitchen and did a load of laundry. The location is also great -- not too close to the touristy part of town but close enough to walk to La Boqueria market. It's also close to several metros which we took advantage of.
In addition to the place, our host (we only met Eloy on this trip) was not only helpful but passionate about Barcelona. He met us at the apartment to explain the locks and gave us a nice overview of the city when we first arrived. In fact he even sent us very detailed instructions on how to get to the apartment from the airlort before our trip and welcomed us with wine and snacks when we got there. We can't recommend Eloy and Maria's place highly enough and would love to stay there again next time we're in Barcelona.
