Calina & Teo were hospitable hosts that offered us tea and welcomed us to their home as soon as we checked in. They offered recommendations for things to do and places to eat. We contacted them before booking about an asthma issue since we saw that they do permit smoking in the space – my friend can't function with poor air quality so we expressed that concern. Over messaging and when we arrived, our hosts were very considerate and accommodating to make sure that wasn't an issue for us during our stay (the scent of smoking was residual just from the habitual smoking in the space but not an issue at all as far as air quality goes; plus, the guest bedroom door had a great seal so we couldn't smell anything in our room!). The flat was surprisingly spacious for Central London and very clean. Nice space! Friendly hosts!
