Carlo's place was great, and reasonably priced around sixty US for an in-town location. 3-4 blocks walk to Old St. and Barbican Underground stops, and Angel is close too, plus plenty of buses. The place is super clean with plenty of room in the refrigerator. (I didn't cook anything there)
we had a bit of a mix-up on my arrival, which I messaged as 12:30pm at Gatwick. unfortunately Carlos thought that was after midnight, and not noon. but he left the keys outside for me, and I got in no problem. Also, he was very helpful at checkout, allowing me to leave my suitcase there and pick it up later in the day since I wasn't leaving london until 7pm. I would definitely stay again in this clean place and convenient location.
