The apartment was nice and comfortable as suggested by the description and photographs on the airbnb site. Though actually not very large, it feels spacious because of the clever lay-out and choice of furnature (which moreover is a admirably tasteful combination of vintage 50-ies and present-day practicality). The facilities (bathroom, kitchen) are absolutely up-to-date and practical. ---
The house is in a decent and characteristic neighborhood (Principe Real), fortunately not yet overrun by the tourist stream. There is a choice of restaurants around the corner, but there are also various food shops and a small supermarket close by. ---
The center of the city is not far, though it takes some uphill and downhill walking, but this is probably the case for any Lisbon apartment. For plant lovers: it is very close to the Lisbon botanic gardens! ---
One minor downpoint: there can be some occasional noise from other apartments, but not more than is inevitable in this type of building. ---
Reception by Cristina's husband Ricardo was punctual to the appointment, and moreover very friendly and helpful. Both before and during our stay Cristina kept in touch by e-mail, providing useful advice and assistance. ---
In summary: a superb place for a visit to Lisbon and surroundings.
