I had a lovely (short) stay in the Together house. The initiative is great - everything is shared and people collaborate to make a nice place to live & enjoy. It's a social and open atmosphere so it'd be quite easy to meet people if there are othere staying.
The location is in a nice, quiet and safe neighbourhood, close to the lively Trastevere centre, but it's quite a walk if you want to get to the other side of the historical centre (no metro nearby, and I found the buses/trams a little complicated). Plenty of good food places nearby!
The house was great - one of those lovely old listed buildings - and it's very nicely decorated. The room itself was OK - it's a bit of a shame the door wouldn't properly close (also, there's no lock, but I never felt unsafe or anything - just take your valuables with you or put a lock on your suitcase), and it wasn't as clean as I'd have liked. The floor could have used a good sweep and the mattress/duvet wasn't in great condition (likely due to some guests not bothering to use the sheets provided (in a sealed package, which is great!), this could be emphasised), and I would have liked a proper duvet cover instead of just a sheet (for hygiene reasons). However, there was a woman who did the cleaning and she comes by quite regularly I think, so the bathroom was very proper :) Also nice hot and quite strong shower in the bathroom I used (far end of hall).
Ernesto was a great host - he wasn't yet there when I arrived but someone opened the door for me. Very friendly and social, but always allowing you as much space as you like. I had some lovely chats with him during my stay, which taught me something about Italian parents & food, and his vintage record player - really cool, thanks for the memorable and amazing stay!
