Nadia is a welcoming host, we haven't seen her personally, but she left very clear instructions on how to find the apartment, and where do we take keys. Everything was arranged with care and attention which we could feel. We were traveling with the small kids and had a high chair and baby cots and linen and even baby bath. Location is superb, few steps from Ramblas and P.Catalunya. Also what we have valued a lot is a list of carefully selected places to eat, recommended by Nadia - we tested many of them and all were excellent! We would definitely come back.
