Filipe is a super friendly and very pleasant host. You can reach him at any time and he will always answer quickly and help you if there are any probems or questions.
The location is perfect!!! for a stay in lisboa, it's calm and laid back and there are so many things to do (and especially eat ;)) just around the corner. Alfama was our favorite quarter of lisboa. Also you can reach everything else easily: it's all walking distances, or you take the Metro for 1,45 Euros if you are too lazy :)
The flat is quite small, but Filipe did the best of it and the interior is perfekt for a few days. You will find everything you need if you want to cook and the bathroom is nice as well. The bed is super comfy and you can even see the Tejo out of the windows.
One thing you need to know: if you want to sleep in a lot and if you are sensitive against noises, maybe it's the wrong location for you, because in Alfama, the houses are very crowded and a little poorly soundproofed. But we got used to it and it was definetly worth it!
So, all in all we had an amazing stay at Filipes and would recommend going there :)
