The apartment: bedroom, kitchen etc is very modern, attractive and well-maintained.
The bed was very comfortable and the wifi worked perfectly.
I only saw our host on the first day, but she was very friendly and helpful.
I would have no problem at all about recommending this apartment. The only thing people should be aware of is that it is a little far from the city centre, but at the same time it is right beside a metro station, and also near the delightful Gulbenkian museum with its park etc.
