Catherine's place is well located and sparkling clean. It also has possibly the best black out shutters on all external windows we have ever seen and the location is super quiet. There is a big Lidl 500m away.
Great kitchen and easy electric hob. Good A/C.
The hosts are very hospitable. For example, they went out the way to provide an extra blanket to sleep with and kindly accommodated our request for a slightly later luggage check out - which saved our last day's sightseeing plans in Lisbon.
To make the experience even better, we would suggest providing an extra towel per guest, keep an extra blanket/duvet for guests who prefer single duvets and perhaps provide some basic shampoo/conditioner.
