Thank you very much Marcos for your very friendly welcoming.
Very nice looking bedroom and bathroom, with perfect cleanliness. One suggested improvement would be to install sound proof windows as the moscavide street, just under this 3rd floor apartment, can be noisy at times during the night (cars and trucks passing by), and this could be disturbing for people with a light sleep.
Apart from that, everything else was perfect from my point of view. In particular the location is ideal for a quick and easy access by the metro to the airport or the oriente train station (the moscavide metro station is just at a 5mn walking distance from this apartment).
Will keep this address on my preferred list for sure when coming again for a stopover in Lisbon.
