If location and simplicity are top of your list then this apartment is for you. We were delighted by how close the flat was to all of the main sights and train/metro stations that you may need for exploring further afield. It was clean, tidy and fairly well equipped. Isabel was also very communicative and welcomed us warmly.
A few things to be aware of: the flat is on the 4th floor without a lift so, whilst the views it affords are great, accessibility is an issue. Space is also more limited than the pictures make out so parents + 2 children may be quite tight - 3 of us adults coped ok. The area immediately outside the apartment block also felt a little unsafe due to the large congregation of informal vendors - perhaps something to be careful of if you're young female travellers.
