Stayed here from 2-9th July and absolutely loved it!
Joao and Carla made us feel extremely welcome, made sure we arrived safely all the way from Australia (after arriving in the middle of the Lisbon marathon and not being able to access many roads in the city, so Carla helpfully spoke to our taxi driver and helped to organise the best way to get to the apartment!), then met us at the apartment to show us around and explain how everything works.
They also had a lot of helpful information about where to go and what to see in Lisbon and were easily contactable throughout our stay in Lisbon.
The apartment itself is great, has all the amenities and comforts of home and spacious for 2 people (was especially great to have a washing machine/dryer for our laundry)!
It is an approximately 10-15 minute easy and lovely walk from the city centre in a quiet street and also very easy to find a taxi if you prefer not to walk.
I would highly recommend staying at this apartment if you are visiting the beautiful city of Lisbon and I would definitely choose to stay here again the next time I visit Lisbon!
