My husband, three teenagers and I enjoyed our stay at Jose's apartment very much. It's in a lively area with many restaurants around and easily walkable to many attractions. The communication from Jose was excellent, anything we needed, he helped us. The apartment is well stocked, with some basic cooking items and has a washing machine, which was very welcome.
Only a few things to note which may or may not be good for others: (1) the apartment is up three flights of stairs, which was fine for us, but for others with less mobility (or heavier suitcases) this might be tricky; (2) there is no air-conditioning in the apartment - again, this would have been fine apart from the fact we were there during July which is always hot, and that particular week saw a heat wave over much of Europe. Two of the bedrooms have no windows at all, and the heat was unbearable at night, so the two girls slept in the lounge area on the couch. The next day, Jose brought us over two good fans, which made it much more comfortable for them and my son, who was in the third bedroom; (3) the apartment is in a busy area, with many bars and restaurants - the street itself is generally quiet, but there is certainly the sound of music and people if you have the windows open (which we had to because of the heat).
Despite some hiccups, which were not Jose's fault at all, we liked the apartment and enjoyed our stay in Lisbon.
