We had a very pleasant one week stay in Juans apartment.
After a warm welcome, Juan spent a lot of time explaining us in detail where to go in Lisbon, where to eat, what excursion to make. Very nice! :)
The apartment itself was excellent! A lot of light, fully equipped kitchen, even with a washing machine. Very fast internet.
And well located: close to everything you need (supermarket, bakery, ...) and at the same time very quite.
Two viewpoints over Lisbon are within some minutes walk.
We definitely recommend Juans apartment! :)
