For a couple this would have been great, but we had 3 of us. The sofa bed was broken and the only options were to sleep with the coffee table under it (feet well above your head) or as is with it broken (feet well below/downhill from your head). When we asked the host if she knew it was broken (no accusations or language just a question) she said we were attacking her, responded very rudely and threatened to make us leave the next morning. Given it’s a weekend in central Paris and we only had 2 days there was no time to move nor find suitable accommodation elsewhere.
If we had only been 2 people and could have done with one bed it would have been fine. It’s a pretty flat in a nice location.
