The space is beautiful and wonderfully decorated. It's a bit noisy and I'd say a bit snug for 3 people - I wouldn't recommend 4 adults (the couch arms flatten into beds rather than folding out with a mattress). There's also no separation between the main double bed and the coaches (it's a studio).
This wouldn't be an issue for two people at all. It's very nicely kitted out and has a generous bathroom.
