This was a great property for a single traveller visiting Lisbon. The location was excellent and was within walking distance to busses, metro and street cars. The apt was comfortable and had almost everything I needed (I could have used an iron). I enjoyed the small park just down the hill and the restaurants near by. The host was easy to deal with and the interaction was helpful and efficient. I really had no issues with the place at all and would gladly stay there again.
A couple of things to note and be aware of and these are in no way criticisms.
1. To reach the apartment, you have to go up a fairly steep and narrow staircase. There is no lift / elevator.
2. The water heater is on the smaller side, if there are two or more travellers, plan accordingly and shower at different times of the day.
3. Internet speed was outstanding! Better than you'll get in most places.
