My wife's and my stay in the Greenhouse Colosseo was pleasant. We spent 4 nights in the room, giving us ample time to enjoy all Rome and the surrounding area had to offer. I'll just make it easy, labeling the pros and cons of staying here.

Pros:
- Great location! Centrally located in Rome, close to all the sights/restaurants/bars.
-Portable wifi is a fantastic feature available for traveling around the city/driving (GoogleMaps saved us multiple times).
-Very friendly at arrival.
-Very quick responses to questions/concerns we had throughout our stay.
-Good "insider" information on where to eat and have some of the best cappuccino.

Cons:
-The portable wifi is your ONLY source of internet. So while it is beneficial when you're out and about (using GoogleMaps), by the time you get back to the room, the internet gets slow and unable to do research on what to do the following day.
-Ask for the AC controller upon arrival. Glad we did, because it gets warm in the room. You can open the windows, but then you allow the bugs in.
-Garden space was a bit overgrown and "buggy". Would have been nice to have a glass of wine out there during sunset.
-Laundry service was paramount during our 2 week trip and was one of the reasons we wanted to stay here! While it was worth 10euros (we had two loads of laundry) to wash all our clothes, all of my white T-shirts are now forever tinted blue...forgot to separate the darks from the lights.
-Poor towel change. Granted, the Hosts were on a weekend trip, but before they left or immediately returning, it would have been nice to have fresh towels. We had to reuse our towels for 3 days.
-Beware of the municipal tax. While it is included in the description saying "3euro tax", this is NOT included in the overall price with AirBNB, AND it is 3euros per day & per person. A bit caught off guard when we needed to pay another 28euros upon our checkout. Also, since nobody was around to collect the 28euros and give us our change, we opted to pay online. In just 2 days we were sent to a resolution center for not paying. Well we didn't have any internet over those two days.
-The two rooms share a kitchen, luckily we had pleasant/quiet roommates. But the entire time, we were "tiptoeing" around, not to make too much noise.

Overall, a good experience, friendly hosts, and great location, but my wife and I are unsure if the pros outweigh the cons. Grazie Valentina, for allowing us to stay with you.
