Lucia warmly welcomed us, even though we were 15min late (we could not find the right way from Rossio station, we walked around a little and wasted time). The flat was how it appears on pictures, clean and tidy, perfectly situated for those who are on foot only, in a really nice street, quite animated some nights (ear plugs needed), an authentic Lisboan cachet. Little surprise though : toilets flush wasn't properly working, we handled it without any trouble (shower is right next to it). The real tiny annoying detail : Lucia warned us the plumber was to come, Euriko (William's father who lives upstairs) was supposed to call us, so that we may arrange day and time. He didn't, and we discovered him inside the flat whith the plumber, when we came back, that is around 8.30pm. He seemed to find it normal. He probably wouldn't have bothered calling us, if we had come back late enough so that our paths never crossed. He explained the plumber was to come again the next day. Next day : no call again, and found him in the flat once we headed back, again.
Nothing was missing, still he remains nice, we just find strange and rude to simply go in people rental with no call, at all.... No permission asked.
Anyway, that did not ruin a thing, Lucia was worried to make our vacations pleasant. Lisbonne is a must-see, we had great days over there !
