Hugo's flat is absolutely lovely!
It is well located, not too far from the city center, close to the metro station Anjos and with a supermarket, small bars and grocer's shops all around the neighbourhood where you can have very cheap and good breakfast and buy whatever you need.
The neighbourhood is quiet but not boring, very typical.
Inside, the flat is nicely furnished, freshly renovated and very clean, and can very well accomodate up to 4 people (we were 4 girls for example).
There is air conditioning in both sleeping and living room, but we didn't really need to use it.
And of course the big terrace is definitely a plus: it is always sunny, with beautiful plants and flowers, perfect for chilling outside and having an aperitivo in the evening ^^
The host was always very responsive and helpful, he even let us modified the booking twice within Airbnb regulations and left a bottle of wine for us in the flat and some other basic groceries.
On a side note, when we arrived there was a bit of humidity on a wall, but it didn't bother us at all, the host just could not make it in time to paint that spot new. There were also some construction works at a nearby building, it was a bit annoying sometimes, but that is just a temporary inconvenience the host is not responsible about.
In conclusion, we can just recommend this place (and Lisbon, such a nice city!!!) and we would definitely come back if we had the opportunity :)
