The check in was fine, the apartment was clean, the lockbox is a great idea. The apartment was really well located for every attraction in Florence. Good communication from Horia throughout the process from booking to arrival. The bathroom is quirky in the way it is laid out. There were some light bulbs out so the sitting room wasn't as light as it could have been and one of the bulbs flickered when the light was turned off. If you slept in the bedrooms this wasn't an issue but if you were on the sofa bed it might be an issue for you. Wifi was good.
We had to leave a day early due to problems with the boiler and no heating (at the end of December) but Horia refunded a night and offered to let us stay the full 5 nights if we wished. Unfortunately as the problem occured on the Sunday and Monday (New Years Eve) it couldn't be fixed when we were there but Horia was apologetic about the issue and sourced extra blankets etc and brought wine to apologise. It was just an unfortunate event at the wrong time of the year. We did have hot water so showering and washing up was fine. The beds are really big and comfortable and the apartment is pretty quiet for a city centre. The stairs are fine if you are fairly fit and healthy but if you have mobility issues you might struggle.
