Silvia and Ricardo's flat is one of the cleanest and complete places we stayed.
The check-in instructions were very clear and it was very easy (and funny) to get into the flat.
The flat itself isn't big, but we felt there was plenty of space, as it is weel thought and organised.
Everything you need for a short stay is there, from shampoo to coffee to a first aid kit. The flat has plenty of instructions around it, and it is very easy to either use the appliances or to know where to leave your bin.
It is from walking distance to Porto's main attractions, and also close to Gaia's commerce. We could have reached Porto with the metro (which is very close), but we actually walked with our 6 year old twin daughters.
When we needed help from the hosts, they were very quick to answer and solve our problems.
Porto is one of those cities we'd like to go back to (this was our second time), and so it is Ricardo and Silvia's flat.
