We didn't expect that our apartment is SO close to railway-station (meaning noise from trains that come and leave late at night and early in the morning). If windows are closed you don't hear the noise, but it is very stuffy and there are no air conditioners. So, we had to open the windows and had to accept the noise. Wi-Fi worked poorly, enough to send messages but not for conversation or checking things in Internet. Other then this, the apartment was nice and had everything we needed. It is very well located - easy to get everywhere in Sintra.
