We had a great week in Lisbon staying at the Lighthouse apartment.
The apartment is really comfortable and has everything we needed. The swimming pool was quiet during our stay. This is mostly a residential block, so not touristy.
The apartment is really good for local transport. The train is easy and frequent to get to Lisbon or Cascais.
There is a local beach across the road with a beach bar / cafe, but Cascais really easy to get to as well.
Ana was so, so helpful and friendly and made sure we were happy and had everything we needed (ie corkscrew!
She had even left us a bottle of wine when we arrived.
I definitely recommend you stay here!
