Hi,
I stayed at Anna's for 4 nights in mid-December. It's a very interesting and attractive flat, in a very convenient location - it's very easy to get to La Placa Catalunya, the airport, the supermarket, and with a couple of cinemas nearby.

There is some street noise outside, especially at the weekend - it didn't trouble me at all but might disturb someone who is noise sensitive.

The bedroom is very comfortable, and warm (important in December!) and met all my needs.

Anna herself was very friendly, courteous and welcoming, and gave me her phone number in case of any trouble.

This was my first experience of AirBnB, so don't have much of a benchmark, but for me it was a very positive experience, and I would stay there again on another trip to Barcelona.
