In full honesty, Dolores was a wonderful host. I stayed at her lovely apartment with three other friends, and it was absolutely great. The apartment had everything we needed, it was just as adorable as in the photos. Everything was new and clean. We were there in June, and we thought it might be too hot in the apartment (it's on the top floor), but it was actually quite fresh inside and perfect for sleeping.
The location is just perfect, it's in the centre of Bairro Alto neighbourhood. That neighbourhood is full of bars which are busy almost every night. But Dolores' apartment is 5 minutes away from them, so her area is quiet at night, which was perfect for us - we were able to go out for drinks, and still get proper sleep! We even ran into her in a bar one night and had some drinks with her... she is incredibly funny and very pleasant to be with :)
Our stay in Lisbon was great, and I would gladly stay at her apartment again next time I come.
PS. One tip.. We discovered the loveliest local bakery/pastry shop, 2 minutes from Dolores' apartment, up to the end of the street, and there on the corner with R. dom Pedro (right side) there's this great bakery, truly an authentic taste of Lisbon.
