We stayed at Cristina's place for one month in February with out 1yo son. The apartment is beautiful, nicely renovated and clean with a great location just a few mins walk from Praca Das Flores where you can find great cafes and restaurants etc. The apartment is well equipped with everything you need for longer stays as well as short visits. Cristine is a great host and was very helpful, giving lots of info on the local area and Lisbon in general. The only negative is that the apartment can get a little cold if staying in the winter months, but we are sure this means would be nice and cool during the hot summer too. All in all highly recommended.
