I had a great 4 days at this excellent accommodation! It was very clean, comfortable (including the beds - two bedrooms), recently renovated, and had a fantastic private back yard with orange tree. The area felt safe.
It was a very short walk to all the attractions in Belém as well as to the bus, tram and train stops for accessing the rest of Lisbon. There was a pod coffee machine, and Ricardo had stocked the kitchen with the basics for breakfast. Internet access was provided with a portable WiFi device, which I could unplug and carry with me during my exploration of Lisbon.
Ricardo also provided a good orientation to the house, how to use the public transport, etc.
Highly recommended, wish I could have stayed longer!
