Overall good experience.
Good location if you want night life, but be prepared for loud, drunk tourists until very late on the weekend. Easy to get every where else after a short walk to metro/bus/tram.
Good sized and clean apartment. Kitchen is small but functional for simple tasks. Don't expect to cook anything elaborate. The bed is very firm, we spent 120 Euros for a mattress topper at IKEA to make it tolerable.
Hosts Nuno and Catia were excellent. Responded quickly and positively to a few small issues.
