The apartment is pretty nice, but you see that it is used a bit and needs some love. But it is still a really nice apartment.
The area is one of the worst when it comes to safety in central lisbon. It always feels a bit sketchy to be around at night and it's not recommended to be alone around here at night. Lot of drug dealers around and so on (Martim Moniz).
The checkin is easy, but I asked some stuff and just got once an answer from the owner.
The wifi is top.
In the kitchen there are definitely some missing stuff (only one little pot, no sieve for pasta, no cutting boards etc.)
It is normally quiet during the night and now noice from the streets. Of course you can hear the other rooms (it's portugal) and the cleaning of the other rooms is pretty load (e.g. vacuum cleaner).
