The Box House is a truly unique, extremely comfortable, wonderful and interesting space, full of conveniences for your visit to Florence. The location might not be ideal for some, but secure (free) parking was a bonus for us - and we weren't worried about the walking distances necessary to get to various sights. There's a clean, convenient self service laundry within a block and a FANTASTIC grocery store a short walk away. We had been traveling for 8 days already, so laundry and supplies were important.
We were lucky enough to meet Alessandro and his charming wife (Sabrina? I hope that's right, I apologize if it's not) - they were so helpful with recommendations and answering any other questions we had. They gave us some really helpful tips, and steered us toward some special events we wouldn't have known about if not for them.
I can't say enough about the place itself. Thoroughly enjoyable, especially for anyone who loves design and the visual arts.
We were fortunately aware that the boiler might need re-setting to provide hot water - but we had plenty and water pressure (as others have mentioned) was adequate.
The kitchen is extremely well- appointed, I think you'd have enough dishes, glassware etc if every seat at the GIANT dining table was full.
If you're an American like us, you might want to bring (or request) extra towels, and I don't think the washer works (but I said above, the nearby laundry was neither busy nor expensive) and there's no dryer anyway.
We had no trouble finding the place, no trouble parking and check in/check out is a breeze. Alessandro was gracious about letting us check in early to accommodate a tour we'd scheduled in advance.
It's a big space and two couples could share, but keep in mind there's only one bathroom. I wouldn't necessarily recommend it for young children (too many fascinating fragile things! ) but older kids would really enjoy it, I think. Mine would have.
For two friends traveling together, the space and privacy it gave us for a couple of days in the middle of a long trip was welcome.
I've covered a lot, but I'm sure I've missed things I planned to praise - suffice it to say I'd 100% stay here again and I'd recommend it to anyone. PS. The wifi worked just fine.
