Rui was a lovely host, very friendly and responded to messages quickly.
He also gave us a lot of helpful tips and recommendations.
The apartment is lovely and tastefully decorated and we enjoyed the little patio. The double room is very nice and quiet. The bed was really comfortable and air conditioning great and nearly silent.
The attic with single beds would be great for kids.
The location is 5 minutes from a train station which gets you into Lisbon in 10-15mins or Cascais in just under 30 minutes. I would definitely stay here if visiting Lisbon again.
