Value for money product. I bought it mainly because of its pop-up setup method and its good waterproofing (which luckily I haven't had the chance to test yet). I think it would be borderline for 3 people. It has a very low height. It is quite narrow due to its design, and I mean that the inflatable mattress (double) barely fits. Finally, I should note that unlike usual, the mattress should be inserted parallel to the entrance and not vertically. If it is inserted vertically, it doesn't fit, or it will fit barely, resulting in the mesh not closing. Personally, I will keep it for small and quick getaways, but for longer vacations, I will buy a larger one.
