HomeHouse Borgo Pio 195 is literally 5 minutes walk from the Vatican City and was a perfect place to rest after walking all day exploring Rome!
Guglielmo was very helpful from the start. He provided detailed information about the house beforehand and (although sometimes delayed) responded to any questions I had with informative answers. Upon request, he even set up a driver to pick us up at the airport which was super convenient for us. The ride was smooth and our driver (I forgot his name) was super helpful and kind!!! We had a bit of trouble locating Guglielmo when we first got to the house and the driver stayed with us, making calls for us etc until we got in touch with Guglielmo. (He was actually just around the corner getting some shampoo and body wash for us)
The only thing is that the house is not smack in the center of Rome (it is located between the Vatican city and the Castel Sant'Angelo) but it was a nice walk to the city center. The neighborhood is lively but not too touristy, there are many local cafes and eateries which we didn't have the pleasure of enjoying since we were out and about all day, but there were quite a few that had good reviews that we would have liked to try had we had the time.
The house was tidy and spacious for the two of us, however one of the neighbors were up VERY late at night and with everything so quiet we could hear echos of their LOUD voices that were probably traveling through some pipes. It was disturbing - especially at 3am!! I had trouble sleeping the first two nights due to all the noise but it seemed like they were actually moving out of the apartment since we saw a moving truck on the third day and I slept like a baby with no disturbance that night. :)
The wifi wasn't working properly and Guglielmo got us a tablet to use as a hotspot which was SOOO convenient!!
The pros: lovely neighborhood, house is spacious, bed was comfy, sheets were clean, hot water was plentiful, the bathroom appliances seemed really new and there was more than enough closet space to hang all our clothes.
The cons: shower may be a bit tight for taller/bigger people (it didn't really bother us) and it seemed that the living room ceiling (which is unfinished brick) was raining little bits of stone dust. It didn't really bother us but if you're sleeping on the sofa bed (which we didn't use) it might be a problem.
All in all we really loved Guglielmo's place. It was absolutely perfect. :)
