We enjoyed our two-night stay at Rita's place in Sintra. It's about a 5 minute walk down into the old town, and an 8 minute walk up.
The apartment is clean, compact and convenient. A good kitchen area...perfect for a short stay. The upstairs isn't for tall people! You'll have to stoop to get into bed, but it's bearable for a couple of nights.
Rita is a lovely, welcoming host.
