For the most part, my partner and I had a good stay at Tafon's place (only one night). It's fairly well-located in central London. It's about a twenty minute walk from Trafalgar Square and only about ten minutes from Covent Garden). It's also a short walk to Goodge Street tube station.
Tafon is also very nice. He was responsive to our messages and was very kind to help us carry our heavy luggage up several stairs (guests should be aware that the flat is on the third floor and you have to climb several steep flights of stairs since no lift is available). The room itself was more than adequate for the night we spent there.
Our experience would've been excellent were it not for an unfortunate - and unsettling - incident regarding Tafon's wife on the morning that we checked out. We asked Tafon if we would be able to leave our luggage at his place after we checked out since our flight was in the evening and we wanted to explore central London a little more, to which he kindly agreed. He only asked that we leave the keys by 11 a.m. (the check out time). We went out for breakfast and returned by 10:20 a.m. (forty minutes before check-out) and, when we arrived at the base of the steps, his wife very rudely demanded the keys back, scolding us like children. This terrified us and in fact ruined my fiance's last day in the UK. We've never experienced anything like that and cannot understand why we were addressed so rudely. I must reiterate that we were not late, we had asked if we could leave the luggage, and we had been very polite, clean, and quiet. Tafon had told us earlier that they had guests coming but we checked their Air BnB page (before we asked if we could leave our luggage so that we wouldn't be imposing) and their place was still available for booking on Air BnB as of late-morning. This marred what was otherwise a good experience considering that Tafon was very warm and helpful and the place is well-located and was comfortable enough for the night we spent there.
