I generally did not have a good stay at this place last time. I am a well travelled person in both Europe and low-and middle-income countries. Therefore, i try to be just in my reveiw.

On my arrival, it was a rainy day in Lisbon. Yet, the building had no plate number to know which one is building number1 in the given street. I had received a text message from the host that they will be at the flat awaiting for me. However when I arrived, i received a text that the key was kept with the laundy shop near the flat. The people working there also did not know the key belonged to which building.
Under that heavy rain, i was pushing my heavy suitcase in the slopy street trying to find out the correct building! After i called back the host and he asked someone in the neighbourhood (persumebly the cleaning lady) to come and open the door of the building. then one of the neighbours started shouting with verbal abuse! It was apparantly due to some problems amongst them or maybe he was not happy with strangers entering the building!

the flat is located on third floor of an old building no sound or heating isolation. the staircases were quite dirty and to take luggege up to third floor was a big problem!
I ended up injuring my back...

then there was not even a kettle in the flat. The host came to see me later that day and he tried to explain things.. which were not convincing to me.

At night, you can hear the next door neighbour's TV and people's conversations in the building clearly and of course the flat was freezing cold. I asked if the host has a heater but he did not provide any.
The pillows and the blue carpet in the bedroom smell!!!

In summary, the flat is not as good as what you are expecting. I was quite disappointed!
