We had a truly excellent stay in Lisbon! The location of the apartment was great, right in city center. Everything was in the immediate proximity yet we had no problem concerning the noise: it was quiet and we could sleep well.
The apartment was clean as well.
We were visiting as a family of six and sometimes we have problems in connection with the size of table or the quality of the extra beds. However this was not the case, the table offered us ample space to dine and even the couch was comfortable to sleep on. Recommended for larger companies!
At last but not at least the internet connection was quite fast as well!
