Great apartment in such a fabulous location (in the middle of the beautiful old city, but within walking distance of everything), on a stunning square full of buzzing restaurants/great buskers etc. The apartment is exactly as in the photos, and has everything you need for a great stay (included a lovely little bottle of port on arrival, which was a very nice touch!) Carlos was also a brilliant host; very responsive in communications before our stay, and so helpful with advice when we arrived.
Only think I would note is that the apartment can be quite loud, because of the square below. Heavy sleepers (like my boyfriend!) won't notice, but if you're a light sleeper like me, bring ear plugs or noise-cancelling headphones (mine worked a treat) and you'll be fine.
