We had a great time at Rosa's flat. We are a couple with a 16-month old and it was a great size, we didn't need anything bigger. Free wi-fi was a big plus, as was location, in a part of Barcelona we hadn't been to before but only 20 mins walk from La Rambla. Rosa was super helpful and kind - we had an issue with the heating, but she quickly solved things by bringing us some extra heaters - perfect! Also, having access to Rosa by email meant we didn't have to make phonecalls, just send her a message via the wi-fi and she got back to us straight away! Would highly recommend the flat for a couple or couple + toddler like us. :)
