My friend and I stayed with May for eight very good days.
We felt at home from the beginning, May has a very nice place and a very nice room mate too.
The flat has a perfect location. You can walk 1-1,5 km in every direction and you will find a special sight. - for instance La Sagrada Familia. It is even closer to the Metro and busses.
May rents out two rooms on a regular basis, and that makes everything very easy, bacause she knows what she is doing. On top of that she is very helpfull and sweet.
We would highly recommend staying with May.
