Although a little bit provisional (e.g. no cupboard), we can recommend the flat for a short stay in Lisbon. It takes around 20min to walk to the center but there is also a tram. The balcony is very nice, especially for breakfast and dinner.

One may note three things:
1) Unexpectedly one has to share the balcony with another flat (which was no problem for us).
2) The house is relatively clairaudient.
3) The communication was not so easy on the day of arrival (although everything worked).

We had a really nice stay in the appartment, thanks for the accomodation!
