We stayed in Piazza dellà Libertà in late January and everything was great! The room was nice and clean with a spacious private bathroom and a lovely common kitchen which we shared with other people staying in the property. We wished it was our own apartment :) The location was absolutely perfect! Located just around the corner from Cola di Renzo, one of the main streets in Rome with loads of lovely shops and places to eat. Just about 10 minutes walk from the Lepanto bus station, 15 minutes walk from St Angelo's castle, the Vatican city and many other beautiful places. We walked pretty much everywhere! :)
The only inconveniences is that the bathtub was quite awkward for showers. Perfect if you want to have a bath but for a quick shower there was no curtain so basically the floor ended up being all wet. Also, the breakfast was quite poor for what we payed. There was only the option to have a few pieces of bread, biscuits and a coffee or a tea. You can buy your own food if you feel like having more but taking into account that it costs us just as much as budget hotel we were expecting a bit more variety.
If you want to leave your bags after check out there is an extra charge of 10 euro. Not quite sure the reason for that as they could be left in the hall or with the concierge of the building. We ended up taking the bags with us and we left them in the train station lockers. It only costs us 7 euro.
These little things were the only inconveniences, no big deal as we had a great time and everything went well. We would definitely recommend it! :)
