Introduction
San Telmo is one of the oldest neighbourhood of Ciudad Autonoma de Buenos Aires. Prepare yourself to walk a lot, some parts of the neighbourhood could be very dangerous at night or on Sundays when there are fewer people on the street.
At Sundays on Defensa Street, you can find a nice craft fair that goes from Plaza de Mayo up to Plaza Dorrego, we recommend to visit Defensa street on Sundays since it will have fewer cars and you will walk more freely.

Defensa
There are a lot of old churchs in San Telmo and several museums to visit. All subways except for "H" will finish at Plaza de Mayo or very close to it. In this article, we will cover walking from Plaza de Mayo to Parque Lezama on Defensa Street. Near Plaza Dorrego You will find many things to do and visit.
The best hotel in San Telmo
Kenton Palace is a great hotel to book for you to stay in Buenos Aires. The hotel is close to everything in San Telmo and since it's very close to Plaza de Mayo you can take subway or buses that will allow you to travel to almost any place in the cicty.
You will be amazed at breakfast at this hotel!

Kenton Palace
Half block from Kenton Palace you will find a church called Basilica de Nuestra Senora del Rosario Convento de Santo Domingo. Inside are the remains of Manuel Belgrano, which took part in the Argentine Wars of Independence and created the Flag of Argentina. In front of the church there is a mausoleum of Manuel Belgrano. It's very recommended to visit this place even if you are not religious, due to its history.

If you continue walking on Defensa street you will find several places that sell dulce de leche. Most of the places in San Telmo which sells dulce de leche have a great variety of brands, which could be very expensive. You could taste for free most of them at these places.
We recommend to buy at a normal super market a dulce de leche of the brand "Serenisima" and it particular the one named "Colonial", the only issue buying this is the package.

Our next stop will be the Mercado of San Telmo located at Carlos Calvo 495, between Defensa and Bolivar. The market has several options to eat and all the food is fresh, if you are close to the market you can eat safely here. You will also find antiques which could be a very nice souvenir, like some old knives. The market is not very visited during the week, but on weekends you could see a lot of people.

You will find that some shops sell vegetables and fruits, those shops usually sell export quality. You must buy cherries, plums, pears or any other fruit from the country. You will notice that at the centre of the market there is a place called Coffee Town stand, which offers an excellent coffee. If the day is not too hot, take a rest and have a coffee here.
