Juan is an excellent host. He spoke to the taxi driver on our arrival and provided directions and then met us after midnight to let us in the flat. The flat is very well located 5 minutes from Alfama, 2 minutes from the famous tram and just below the castle.
The flat was functional and comfortable even though small. You can occassionally hear neighbouring flats but nothing intrusive.

Overall Juan made our trip easy and enjoyable and for the price it's decent value. Certainly if you are a young couple wanting to expore Lisbon this is an excellent base.
