Loved, loved, loved Miguel's place! It is in a phenomenal location, the neighborhood is charming, it's very close to Castelo de Sao Jorge, and it's also very close to a metro station. Miguel gave very clear instructions on finding his place (which was helpful because Lisboa can be a bit labyrinthine). He met us at the apartment, even offered to help us get our luggage inside. The apartment itself is just perfect and the view out of the larger of the two bedrooms is amazing! Everything was clean and comfortable.
As far as amenities go: the shower was great, wifi was great, mattresses were comfortable, there is a combination washer/dryer unit.

I HIGHLY recommend Miguel's apartment, if I'm ever back in Lisboa, I hope Miguel's place will be available.
