Dear Teresa, thanks a lot for your feedback. I am sorry that your visit took place in particularly hot days so that one air conditioner was not enough. Anyway we just installed another air conditioner for the loft area.
Regarding the distance from the metro, the (Hidden by Airbnb) maps evaluates this as about 8 min by walking from the flat both to San Giovanni and Re di Roma metro stations. I am sorry that you found the metro stations a bit farther than you thought. However, these distances are clearly indicated in our AirBnb listing where two screenshots from the (Hidden by Airbnb) maps are provided. From these stations (line A) you can reach very quickly the Vatican Museums, Spanish Steps and most other touristic attractions. The Colosseum and the Basilica of Saint John Lateran are in the walking distance from the flat (in 20 and 10 min respectively).
