Rating: 8/10
Room: as advertised. Lovely apartment, with great AC.
Comfort: the bed is very hard, but I think that's common in Spain. Great shower. The kitchen is nice. The apartment is pretty quiet, with minimal noise from the street. You can hear when the downstairs/side apartments go in and out though, or when the cleaners access their storage. The blinds/curtains are a bit strange, and don't fully close or keep out the light, so expect it to be very bright in the mornings.
Amenities: wifi is great! Kitchen is good enough for some simple cooking.
Location: great location for visiting the historic city, and not too far from the metro to the main train station and airport. There is a grocery store three minutes away which has everything you could need.
Price: a bit pricey, but not too bad.
Other: lovely hosts, very welcoming. Thanks!
