We just returned from a 3 night stay at this apartment and we had a brilliant time. The location is perfect, just a short walk away from most attractions. Lots of cafe's, shops and restaurants near by (the tapas n friends restaurant around the corner was soooo good!). The train station to sintra is a 10 min walk away which was great.
The host was always available to talk, we just used whatsapp and they always responded quickly. Check in and check out was super quick and easy and they also arranged a private transfer to and from the airport for us for just 20 euros each way which was good.
The apartment was really clean and the bed was super comfy. At night time it was really quiet, no noise from outside at all, even when we kept a window open. The only thing we felt was missing was an iron and an ironing board, my husband needed to iron his shirt for dinner but couldn't. But apart from that the apartment is a great place to stay and we would definately recommend staying there. Thanks for a great stay!
