Communication from LxWay was very poor: responses to my messages were slow and obtuse, the phone number was wrong and no email address was provided, all of which meant there was no one to check us in when we arrived despite my repeated attempts to arrange a time.
However, the flat itself was spacious, nicely furnished and well-equipped. We found the bed very hard, but that seems to be normal these days so I can't complain too much about it.
The elephant in the room is that the building is literally next door to a night club, so if you're staying here you'd better be a heavy sleeper. The small print in the listing only warns that "noise-free guestrooms cannot be guaranteed", which is such a gross understatement that I'd find it hilarious if I wasn't so sleep-deprived. Music thumping through the walls until 5am tends to destroy my sense of humour. I had assumed that the noise warning referred to the trams, since they pass right outside the windows, and I'm a regular visitor to Lisbon so I know it's not a quiet city. To be safe, I checked Google Street View before I booked, but this club (Incognito) is hidden behind an anonymous green door, so you wouldn't know it was there in the daytime.
As far as I can see I have been deliberately misled, and that is just not acceptable. I won't be booking with LxWay again.
