Maria Inês was a great host, reactive and is a good communicator.
We had a great stay and for the price we paid we totally recommend a stay at this place.
Globally it was great but not perfect because of a few littles things that could easily be fixed by the owner.

We liked:
- The location close to the metro green line - 20min from the center and train stations to go to Cascais or Sintra (a must do!!)
- It was clean!
- the bed and the shower were nice and rewarding after a tiring walk in Lisbon (the city where you never stop walking up and down hills!)
- the space was big enough to feel comfortable
- the check in/out with a key box is always convenient and easy. We could not leave our luggage after checking out because other guests were coming right after us but Maria Inês said it would have been ok if no one had booked after. We found a good locker inside Rossio station (9 euros up to 12h) and the guy who helped us there was a very nice American guy called David (thumbs up for his kindness).
- We were not disturbed by the noise even if we could hear a bit through the walls sometimes. Never been disturbed during the night.
- We didn't notice any bad smell due to bad isolation and humidity (which seems something quite frequent in Lisbon's Airbnb comments). It was a bit cold though in December but the AC could be used to heat the place a bit if needed.
What made us remove the fifth star:
- wifi quality was a bit poor and we lost connection a few times
- the electric power is a bit sensitive and if you try to cook using several appliances and AC at the same time you'll have electric blackouts, which happened to us a few times
- the AC can be used as heater but it has limited range, so in winter you might need to wear a pullover sometimes in the house, which did not bother us that much.
- A few thing were missing or could have been more generously provided from our point of view:
--there was no soap in the shower :(
--only 2 rolls of cheap/thin toilet paper for a week's stay of 2 persons was not enough (thicker rolls and spare ones would have last longer and would have been more comfortable)
--strict minimum in the kitchen without any pepper, cooking oil, sugar, coffee, only one trash bag for the week, the sponge was in bad condition.
Some people complained about the stairs and the fact that you need to climb a steep road to get to the apartment entrance; It is true it is uphill and there are 2 floors, so it would be hard for old people and not adapted for wheelchairs for sure. BUT if you go to Lisbon, don't expect not to be climbing hills all day long because you will !! Knowing that, climbing for 5min to reach the apartment was not such a big deal for us.
This is our honest feedback, probably picky ^^ but the point is to inform the future guests and also to help the owner to improve his service. Some of these points didn't bother us that much (but might disturb others).
Overall we were really delighted by our stay and would definitely tell everyone to go and book this place which certainly is gold compared to other offers around the city !!!
