We chose Renata's place at Entrecampos because of the many positive reviews, and we were not disappointed. Renata also picked us up at the airport, which was great and made travelling with children much easier. She is a very good and friendly host and has advice for everybody, I think. Everything in the flat is like in the description. If you like staying in a lively, completely untouristic district with good shopping facilities (shopping centre under the bull fight arena nearby) and only 10 mins by metro to the centre, this is the place. It is good value and suitable for families because of the two separate bedrooms. Our 10 years old children liked it too. Full recommandation!
By the way: Try the Portugese restaurant round the corner that Renata recommands. No English menue, no English spoken (nor any other language but Portugese), no rip-off, just simple, genuine food and friendly people.
